POLICE in Chester are aiming to crack down on anti-social behaviour following trouble involving teenagers in a city centre park last night (Monday).

The force says due to anti-social behaviour involving a large gathering of mainly teenagers last night in Grosvenor Park on Monday night, it is using dispersal powers to prevent this happening again.

It has set up an exclusion zone, effective from now until 11pm tonight.

The zone includes Grosvenor Park, the Meadows, the Groves and parts of Handbridge including playing fields by Queen's Park High School.

Officers say anyone given a notice will be barred from the area for up to 48 hours.
