Police enforcement may establish an immediate boundary, but formal processing can also bring a child deeper into the criminal justice system. Youth diversionary activities take a different route: they aim to interrupt the behaviour before arrest, prosecution or a lasting criminal record becomes the central fact of a young person’s life.
The evidence does not support a simple choice between enforcement and prevention. It supports a more precise distinction. Police action remains necessary for serious, high-risk and violent offences. For lower-risk cases, however, structured diversion has produced better measured outcomes than formal criminal justice processing alone. The policy question is therefore not whether North East Lincolnshire should enforce the law. It is how enforcement and early intervention should be allocated across different levels of risk.
The shift toward a child-first model
Youth justice in England and Wales has moved progressively towards early intervention and diversion. This does not mean that offending is ignored or that police powers are removed. It means that the response is calibrated to the conduct, the risk presented and the likelihood that formal prosecution will reduce or increase future harm.
The distinction matters because a formal criminal justice response can generate consequences beyond the original incident. Court proceedings, a youth caution or a criminal record may affect education, employment, travel and access to services. In some cases, the process itself can reinforce contact with other offenders and weaken a young person’s connection to school, family or legitimate community networks.
Diversionary activity is designed to intervene before that pattern becomes established. It may include:
- targeted youth work addressing behaviour, relationships and decision-making;
- mentoring and structured community-based activities;
- support for substance misuse, family instability or school disengagement;
- restorative work involving the consequences of harm;
- educational programmes focused on violence, weapons or anti-social behaviour;
- practical support delivered through youth justice, policing and local authority services.
The term “diversion” covers several different mechanisms. It is not synonymous with an informal warning, and it is not necessarily a recreational programme. Effective diversion has an assessment component, a defined intervention and a method for tracking completion or further incidents.
The national data indicates how significant this model has become. Statistics published in 2026 show that around 13,500 Youth Justice Service outcomes in England and Wales were diversionary. That represented 43% of all outcomes for children worked with by Youth Justice Services.
This figure should not be transferred directly to North East Lincolnshire. It is a national measure, not a local incidence rate. Its significance is structural: diversion is no longer a marginal alternative used in exceptional cases. It is a substantial part of the youth justice operating model.
Diversion is not the absence of a response. It is a different allocation of intervention, designed to reduce the probability of a more serious response later.
What the evidence says about reoffending
The comparison between youth diversionary activities and police enforcement is often distorted by the way outcomes are described. Enforcement can produce a visible short-term result: an arrest, charge, caution or court order. Diversion is less visible because its intended outcome is often an event that does not occur later — a further offence, a violent incident or deeper contact with the justice system.
For that reason, reoffending metrics are more useful than the number of initial interventions. They allow policymakers to examine whether a response changes subsequent behaviour rather than simply recording institutional activity.
A College of Policing meta-analytic review of 19 studies found that police-initiated pre-charge diversion for low-risk young people reduced reoffending from 50% to 44%. The six percentage point reduction is not a claim that diversion prevents all further offending. It is evidence of a statistically significant improvement compared with formal criminal justice processing.
The scale of the change should be interpreted carefully. A reduction from 50% to 44% means that a substantial proportion of young people still reoffended. Diversion is therefore not a guarantee of compliance, and it cannot be used as a universal response. It is a risk-management intervention with measurable but limited effects.
The Youth Endowment Fund’s evidence synthesis provides a second relevant metric. Formal pre-court youth diversion programmes were associated with a 25% reduction in violence outcomes among children and young people. Again, this is evidence from a wider body of work, not a local North East Lincolnshire result. But it indicates that diversion can have an impact beyond administrative outcomes such as avoiding a charge.
The practical implication is that police intervention in anti-social behaviour should not be assessed only by the immediate visibility of enforcement. A response that produces a short-term cessation but increases the likelihood of future offending may be less effective than one that appears less forceful but addresses the conditions supporting the behaviour.
Where police enforcement remains necessary
There are clear limits to diversion. It is not appropriate to treat all youth offending as low risk, and it cannot replace formal enforcement where there is serious violence, repeated high-harm offending, credible threats to the public or an immediate safeguarding concern.
Police enforcement has several functions that diversion cannot perform:
1. Immediate protection. Officers can remove a person from an imminent threat, secure evidence and prevent further harm.
2. Accountability for serious conduct. Serious offences require a formal response proportionate to the damage and risk involved.
3. Safeguarding and intelligence. Investigation may reveal exploitation, organised activity, weapon carrying or coercion that is not visible at first contact.
4. Victim confidence. A failure to respond formally to serious offending can undermine confidence in public institutions.
5. Deterrence and disruption. In some circumstances, arrest, charge and prosecution are necessary to disrupt persistent or coordinated offending.
The relevant comparison is therefore not diversion against enforcement in absolute terms. It is the use of the right intervention at the right risk level.
| Issue | Youth diversionary activities | Police enforcement and formal processing |
|---|---|---|
| Primary objective | Reduce future offending by addressing underlying risks | Stop immediate harm, establish accountability and protect the public |
| Most suitable for | Low-risk or early-stage offending where support can alter behaviour | Serious, violent, persistent or high-risk offending |
| Typical mechanisms | Mentoring, restorative work, education, targeted support and community resolutions | Arrest, investigation, charge, caution, prosecution and court orders |
| Main outcome measure | Reoffending, violence reduction, engagement and completion | Arrests, charges, case outcomes, disruption and public protection |
| Principal risk | Inadequate intervention may fail to alter behaviour | Formal processing may deepen justice-system contact unnecessarily |
| Record implications | Some routes avoid a disclosable criminal record | Formal outcomes may create longer-term disclosure consequences |
| Resource requirement | Sustained partnership work and case management | Investigation capacity, custody, prosecution and court resources |
The table also exposes a common weakness in public debate. Enforcement and diversion are often compared as if they pursue the same immediate objective. They do not. Enforcement is primarily a public protection and accountability mechanism. Diversion is primarily a preventative framework.
Economic implications of diversion
The financial case for diversion is linked to the same causal chain as the public safety case. If an early intervention reduces reoffending, it may reduce the future demand placed on police, courts, custodial services, youth justice teams, schools, health services and local safeguarding systems.
A July 2025 cost-benefit analysis by the Youth Justice Board estimated that diverting 10% of children from the formal criminal justice system towards effective support could save approximately £113 million annually. That figure is a national estimate. It should not be presented as a forecast for North East Lincolnshire or as a local budget saving that can be booked automatically.
It does, however, establish the scale of the resource allocation question. Formal processing is not cost-free. It requires police time, custody capacity, legal work, court administration, supervision and, in some cases, detention. Diversion also requires investment, but that investment is often distributed across youth services, schools, local authorities, health providers and community organisations.
The economic calculation becomes weak when diversion is reduced to an inexpensive alternative. Poorly funded diversion can become a referral without meaningful follow-through. A young person may be offered a session, a leaflet or an appointment, while the underlying drivers of offending remain unchanged. That is not an effective programme; it is a lower-cost administrative outcome.
Effective youth outreach programmes generally require several operational conditions:
- a timely referral after the incident;
- an assessment of risk, need and safeguarding concerns;
- a named worker or service responsible for engagement;
- realistic access to activities, transport and support;
- coordination between police, the Youth Justice Service, schools and families;
- a method for recording completion, non-engagement and further incidents;
- escalation routes where risk increases.
This is where local governance becomes important. A diversion scheme may report high participation but weak behavioural outcomes. Another may accept fewer cases but achieve stronger reductions in reoffending. Without consistent metrics, programme volume can be mistaken for programme effectiveness.
For North East Lincolnshire, the unknown is the precise local expenditure split between diversion and police enforcement. That figure is not established by the available evidence. A defensible analysis should therefore avoid claiming that diversion has already produced a defined local saving. The stronger position is that national evidence provides a rationale for investment, while local authorities need borough-level data to measure return.
The legal framework: from LASPO to community resolutions
The legal basis for modern diversion includes the Legal Aid, Sentencing and Punishment of Offenders Act 2012, commonly referred to as LASPO. Within the framework used by police and youth justice services, informal out-of-court resolutions can provide a response without moving every low-level case into formal prosecution.
Community Resolutions, recorded as Police Outcome 8, are one route. Outcome 22 provides for a deferred caution or prosecution in circumstances where the child undertakes an intervention or activity. These mechanisms are designed to avoid giving children a disclosable criminal record in cases where formal prosecution is not necessary and where the risk can be managed through proportionate action.
The legal distinction does not remove accountability. A community resolution can still require the child to acknowledge harm, undertake restorative activity or engage with support. The difference lies in the type of institutional consequence and the way the response is recorded.
There are three safeguards against treating these mechanisms as automatic substitutes for enforcement.
First, the decision must reflect the seriousness of the offence and the level of risk. A low-risk first incident is not equivalent to repeated weapon possession or serious violence.
Second, the intervention must be credible. If an Outcome 22 arrangement is used, the deferred element needs to be linked to a realistic and relevant activity. A nominal requirement with no case management is unlikely to produce a measurable preventative effect.
Third, the decision must account for the victim and the wider community. Diversion should not become a process in which the harm experienced by victims disappears from the record. Restorative practice can help address this, but it must be voluntary, properly supported and suitable to the circumstances.
The legal framework therefore creates an option, not a presumption. The existence of a diversionary route does not mean that every child should receive it, just as the availability of prosecution does not mean that every low-level incident requires formal court involvement.
North East Lincolnshire: applying the model locally
North East Lincolnshire Council’s Youth Justice Service provides local diversion programmes in partnership with Humberside Police. The purpose is to address the causes of anti-social behaviour before formal arrest or court prosecution becomes the default pathway.
That local partnership is material because youth crime prevention in Grimsby, Cleethorpes and Immingham cannot be managed through a single agency. Police officers may identify the incident, but the underlying issues may sit elsewhere: exclusion from school, family conflict, substance misuse, exploitation, unstable housing, poor mental health or association with older offenders.
A police response can identify the point of risk. A youth service or community intervention may be better placed to work on the risk over time. The operating challenge is to connect those functions without creating delay or ambiguity over responsibility.
A credible local model should distinguish between at least four categories of activity:
1. Immediate diversion after a low-level incident. The objective is to prevent escalation and establish a proportionate consequence.
2. Targeted support for repeat anti-social behaviour. The focus is on persistent patterns, not isolated events.
3. Safeguarding-led intervention. The priority is to identify exploitation, coercion or vulnerability that may be driving the conduct.
4. Community-based prevention. The work takes place before an offence and may involve youth clubs, schools, outreach, sport, creative programmes or trusted local organisations.
These categories should not be measured in the same way. A school-based prevention programme may be assessed through attendance, engagement and changes in attitudes. A post-incident diversion programme should be assessed through completion and reoffending. A safeguarding intervention requires measures relating to risk, referral quality and the reduction of exploitation.
This is also where community-led youth engagement strategies can be useful, provided they are connected to a preventative framework rather than treated as general activity provision. A programme does not become crime prevention merely because it occupies young people’s time. The relevant questions are whether it reaches the identified risk group, whether participation is sustained, whether the activity addresses the behaviour and whether outcomes are recorded.
The limits of local comparison
There is a persistent temptation to compare local schemes using headline figures alone. For example, a reduction in reported anti-social behaviour may reflect genuine improvement, changes in reporting behaviour, altered police recording practices or displacement to another area. Incidence rates need context.
The same caution applies to enforcement data. More arrests may indicate increased offending, stronger police activity, better intelligence or a change in operational priorities. Fewer arrests may indicate lower demand, the use of diversion or reduced visibility. No single metric can establish success.
A local performance framework should therefore combine several measures:
- first-time and repeat contact with the youth justice system;
- reoffending after diversion;
- violence-related outcomes;
- completion rates for interventions;
- time from referral to service contact;
- victim and community feedback where appropriate;
- safeguarding referrals and identified vulnerabilities;
- geographic patterns across Grimsby, Cleethorpes and Immingham;
- changes in demand for police, courts and youth justice resources.
This is a more demanding approach than counting arrests or programme places. It is also more useful. The objective is not to maximise either diversion or enforcement. It is to reduce harm with the least damaging effective intervention.
The key metric is not how many children enter a programme or how many are arrested. It is whether the chosen response changes the next stage of the risk trajectory.
Balancing enforcement and prevention
The strongest model is tiered rather than ideological. It accepts that enforcement and diversion perform different functions and that both are required within a functioning public safety system.
For low-risk, early-stage behaviour, diversion is often the more proportionate option. It can impose a consequence while avoiding unnecessary formal processing. The evidence indicates reductions in reoffending and youth violence when the intervention is structured and properly delivered.
For escalating or repeated behaviour, diversion should become more intensive, not merely repetitive. If a young person does not engage, if risk increases or if new information identifies exploitation or weapons involvement, the response must be reviewed.
For serious and high-risk offending, police enforcement remains central. A child-first model does not mean a harm-free model. It means that the child’s age, welfare and developmental position are considered alongside victim safety, evidence and public protection.
This balance also applies to retail crime prevention. Shoplifting, criminal damage and intimidation may begin as low-level incidents but can become part of a wider pattern involving groups, substance misuse or coercion. Retailers, police, councils and youth services need routes for sharing relevant information without turning every incident into a purely punitive case. Equally, repeated victimisation should not be dismissed as an opportunity for another informal intervention.
The quality of the decision depends on the quality of information available at the point of referral. That includes prior incidents, current risk, school engagement, known vulnerabilities, victim impact and evidence of coercion. Without this information, diversion can be offered to children who need stronger safeguards, while enforcement can be applied to children for whom targeted support would be more effective.
A sober projection for local safety policy
The direction of youth justice policy is clear. Diversion is becoming a normal part of the system rather than a peripheral alternative. Nationally, 43% of Youth Justice Service outcomes were diversionary, and the available evidence shows modest but meaningful reductions in reoffending and violence.
The next challenge is implementation. North East Lincolnshire will need to establish which interventions work for which groups, at what stage and at what cost. That requires local measurement rather than the automatic adoption of national averages. It also requires stable partnership working between Humberside Police, the Youth Justice Service, schools, local authority teams, families and community organisations.
Police enforcement will remain necessary. It will continue to provide immediate protection, investigation and accountability for serious harm. But it is a poor substitute for early intervention where the principal objective is to prevent a low-risk child from progressing into more serious offending.
The comparison between youth diversionary activities and police enforcement therefore ends with a practical conclusion. Neither route is sufficient alone. Enforcement manages immediate and serious risk. Diversion addresses the conditions under which risk can become recurrent. A borough that combines both, and measures the results with discipline, has a stronger preventative framework than one that treats arrest volume or programme participation as proof of success.
