An order has come into force allowing police to move on groups they suspect of causing problems in part of Derby.
A Section 30 dispersal order has been issued for the area around Rowallan Way, Chellaston, and will run for six months.
It means officers can order people to leave the area - and arrest them if they return or refuse.
The move is a response to complaints from residents and businesses about anti-social behaviour, police said.
The order also gives police the power to take unsupervised under-16s home after 9pm.
Sgt Dave Stafford, of the Chellaston Safer Neighbourhood Team, said: "The benefits of the order far outweigh the time taken to identify and prosecute those individuals.
"We have implemented these orders in different areas of the city and they have proved very successful in helping to tackle anti-social behaviour."
Signs outlining the areas covered by the order will be positioned in prominent locations.
The order covers Rowallan Way, Rosyth Crescent, Carradale Grove, Knights Road, Courtway Crescent, Holmleigh Way and the footpath to the rear of Kildrummy Close.
