Bangor under-16s night-time curfew begins
There is fresh debate about how best to tackle anti-social behaviour in Welsh town and city centres.
In Bangor an order comes into force on Monday night which bans under-16s from the city centre at night unless they are accompanied by an adult.
The police say they will only enforce it if there is disruption. But critics claim the order is heavy handed and unnecessary.
