ARMED anti-seagull vigilantes have carried out attacks in Falmouth causing damage to homes.
Police said they had received five reports from residents whose windows had been damaged by pellets.
The force said it was illegal to kill the birds in most circumstances but it was concerned by the damage to property and the danger of people being hurt by stray shots.
PCSO Sean McDonnell said: "In the past few days we have had reports of cracked windows and it is somebody who is firing indiscriminately above rooftops and that seems to be at seagulls as well.
"There are certainly people out there with gripes and they do try and pop seagulls off.
"It only takes somebody to have a window open and you can cause some serious damage."
It is against the law to fire air guns in a public place.
The incidents have taken place mainly in the Kimberley Park and Berkeley Vale area but also near Greenbank.
PCSO McDonnell said: "Around Kimberley Park there are a lot of seagulls and there have been problems with bins being left out.
"The point is it's dangerous and unsafe. If seagulls are a problem then please seek proper advice from pest control or the council rather than taking it into your own hands."
The police warned that any reports of people using any pistols or rifles illegally could result in the firearms team being called out.
