Police are investigating and increasing patrols following a series of anti-social behaviour incidents in Chatteris.
Cars and mopeds are being driven dangerously along the High Street and those driving and riding them have been gathering at Furrowfields car park.
There have also been three reports this month of a BB gun being fired from vehicles, twice in the direction of members of the public, near The George Hotel, in High Street, and in London Road.
A resident of London Road also reported pellets causing damage to windows at his home.
No one has been injured but several complaints have been received this summer.
Sergeant Jason Hunns said: “Tackling anti-social behaviour is a priority for the force and we will not tolerate behaviour that affects local people in this way.
“We have increased patrols in the area and inquiries are ongoing to catch those responsible.
“I would urge anyone who has witnessed any incidents or has any information, to contact police. We need to know exactly where it’s happening and when in order to target it most effectively.”
Anyone with information should contact Sergeant Richard Lugg, at March Police Station, on 101, or Crimestoppers, anonymously, on 0800 555111.
