On a typical morning at Lambeth police station almost all cells are full. But for the younger inmates there is now an opportunity to turn their lives around.
Within the first few hours of being locked up in a cell volunteers from a scheme called Divert will do their best to guide them away from a life of crime.
There's no shortage of people being booked into the cells at Lambeth. Crime involving young people is at record levels.
The Divert scheme runs alongside the criminal justice structure but it's independent and is not a way for those who have been arrested to avoid the system.
Of the 5,000 young people taken into custody in Lambeth in the last 12 months only 200 chose to engage with the Divert programme.
But it is making a difference. Aaron Burdon, 30, has been in and out of detention centres and prison since he was 12-years-old. The Divert programme got him his first ever interview for a job and even made sure he was suitably dressed.
Aaron got the job and has vowed to stay away from crime. Still in its infancy Divert's successes may be limited. But the difference the scheme makes to individuals' lives is immense.
