A dispersal order will start in Southsea from Monday.
The order – which will cover Orchard Road to Goldsmith Avenue and Telephone Road – will mean that police and police community support officers will have the power to disperse groups of two or more people causing or likely to cause anti-social behaviour.
If someone remains in the area, after being told to leave, they can be fined up to £5,000 and face three months in jail.
Officers will be able to use powers to disperse groups during the order’s six-month trial – which will be reviewed after three months.
Inspector Steve Hutchings of the Southsea Safer Neighbourhoods team, said: ‘People living in the area surrounding Orchard Park have told us about a number of anti-social behaviour issues such as noise, vandalism, public order offences and rowdy and inconsiderate behaviour taking place in the park and the surrounding areas.
‘We clearly cannot allow this sort of behaviour to continue, and with the backing of local residents, we are putting this order in place along with other measures to address the problem.’
