A van selling coffee and sandwiches from an office car park doesn’t sound like anything special, but there’s one in Swindon helping to keep young offenders out of custody. It’s part of an approach being deployed across the country trying to prevent young people from reoffending by encouraging a shift in their identity.

The idea is to get to know the young offender, figure out what makes them tick. And then, instead of locking them up, find ways of getting them involved in whatever interests them. Selling tea and coffee from the burger van is where those with a culinary eye can learn new skills and start to feel valued for being part of legitimate endeavours. Similar interventions include social enterprises working in bicycle maintenance, hair and beauty and podcasting.

As the adult prison population has soared in England and Wales, the number of under-18s behind bars has dropped markedly in the past 20 years, from around 3000 to 400. File on 4 Investigates spends time with the Youth Justice Service in Swindon to find out how it rehabilitates young offenders in the local community, and asks if the success of the youth system could hold lessons to address chronic overcrowding problems in adult prisons.

Chris Marston, who presents shows on National Prison Radio and spent 10 months in prison discovers that what’s going on in Swindon is very different from his own experiences of the adult criminal justice system.
