Young people in Jersey are being shown how crime can ruin their lives. On Saturday, the Prison Me No-Way! Trust will let them experience being locked up in a St Helier detention cell and also display hard drugs.
It claims none of the young people who have taken part in the scheme in the last four years have been sent to jail.
The organisers of the event, which includes the police, fire, ambulance and prison services, say it has led to a fall in anti-social behaviour.
The trust's main aim is to make young people aware of the causes, consequences and penalties of crime and the effects of anti-social behaviour on themselves and others.
