In the car followed by police helicopters sits "Hassan". This is far from his first, or last, crime. He himself says that he committed his first robbery as a 12-year-old and has long been well known to the police.

"Everyone, more or less, kept going and chasing him without us wanting to chase him because we could see what the result was in the form of mad runs," says Magnus Nilsson, municipal police in Järfälla.

Today, "Hassan" is 19 years old and is in prison for, among other things, robbery.

Mission Review has mapped out "Hassan's" life to see how the community manages to deal with young relapse criminals. You can read more about it, and see an interview with “Hassan”, here.

The entire report "Young and criminal" will be broadcast on SVT1 at 20.00 on Wednesday 18 September - you can see it already at 12.00 on SVT Play.
