Anyone aged 10 or over can be given an Anti-Social Behaviour Order.
Thousands of Asbos have been handed out since they were introduced in 1999.
Similar to an Asbo is an ABC - an Acceptable Behaviour Contract, which sets out voluntary rules in a more informal and flexible manner.
As part of rules brought in with the Anti-Social Behaviour Act 2003, areas can be made "dispersal zones".
This gives police the power to ban groups from certain areas where there are problems.
In these areas, officers can also take kids home after 9pm at night if they are not with a responsible adult.
