There will be extra police patrols out in Lancaster city centre over the weekend.
The move is a response to complaints regarding anti-social behaviour from local residents and the business community.
Lancaster’s Neighbourhood team will be out and about to tackle this using a variety of tactics, including plain clothes officers.
A spokesperson said: ‘’(They) have told us there is a problem with anti social behaviour in the City Centre, so watch out! Parents and guardians be prepared, if it’s your child causing an issue, we will be contacting you to come and collect them.’’
