Following reports of large groups of youths causing disorder in and around the shopping centre in Milton Keynes, police have authorised a Section 34 Dispersal Order to keep the area safe.
The order will remain in place for 24 hours - in force until 18:12 on Sunday evening.
"Our priority is keeping the public and local businesses safe," police said.
The dispersal zone covers Silbury Boulevard, Saxon Gate, Marlborough Gate and Avebury Boulevard.
> A dispersal order allows officers to direct individuals or groups to leave the area if their behaviour is likely to cause harassment, alarm, or distress. Failure to comply is a criminal offence.
