Police Step Up Half Term Patrols
Police have told Heart they'll be doing extra patrols - to make sure teenagers aren't causing trouble in north Bournemouth during half term.
As the evenings get lighter, they traditionally receive an increase in reports of incidents of anti-social behaviour.
The extra patrols will mainly focus on the areas that experience problems and will also check on known offenders.
During the week the dedicated officers will visit vulnerable and repeat victims of anti-social behaviour to check on their welfare and advise them on how they can reduce the likelihood of experiencing further anti-social behaviour and report incidents to the police.
Sergeant Andy Edwards, who is coordinating the operation, said: “While we don’t expect any problems this half term, we are taking all the necessary precautions to protect vulnerable victims and prevent anti-social behaviour from occurring in the first place.
“I would encourage any member of the public who is experiencing anti-social behaviour to contact Dorset Police on 01202 222222. Remember, if a crime is in progress or life is in danger, always dial 999.”
