Kids spend night in police cell
Kids in Cardiff have spent the night in a police cell - but they haven't broken the law, they're doing it to learn about what happens when you commit a crime.
It's part of a scheme that hopes to put kids off breaking the law.
Before getting locked up, the young 'criminals' have to hand over their belongings, put on a prison uniform, and have their fingerprints and mug shot taken.
Hayley went along to see how kids found it - and whether it has made them think twice about crime.
