More than 30 people have been ordered to leave Eastbourne town since a dispersal order came into force last month.
A total of 37 people acting in an anti-social behaviour have been told to leave since July 21.
Under a section 30 dispersal order anyone committing such behaviour along Eastbourne seafront or the heart of the town can be ordered to leave and not return within 24 hours by police and Police Community Support Officers.
If they refuse, or return within that period, they can be arrested.
As of August 12, 37 people have been dispersed, five have been arrested for breaching the dispersal order and one man charged with breaching a dispersal order.
Arden Lindo, 46, of no fixed address appeared at Hastings Magistrates’ Court on August 9 and admitted breaching a dispersal order. He was given one day’s detention, fined £73 and ordered to pay costs of £85.
Sergeant Julian Williams said, “Since the dispersal order has been in place, officers and PCSOs have used the extra powers fairly and robustly when the circumstances dictate.
“Where appropriate offenders are being arrested and kept in the cells to appear before the courts.
“This court result is one of a number of court cases impending for breaching the dispersal order.
“We shall continue to enforce the order until it expires on October 27 when we can assess how much impact it has had on the reduction of crime and anti-social behaviour.”
The powers are available under section 30 of the Anti-social Behaviour Act 2003.
