Staff at a medical centre in Thrapston say they are being intimidated by large groups of teenagers who leave piles of litter and have caused extensive damage.
Michelle Bell, assistant practice manager at The Meadows Surgery, in Meadows Lane, says problems began about two years ago but have become worse in recent times as the young people have got older and begun bringing cars.
She added that the police were contacted on Monday morning because extensive damage was caused to the rear of the building on Sunday, including broken drain pipes and guttering, broken CCTV cameras, an air vent was damaged and lights were smashed.
Piles of litter were also left behind.
Michelle said: “Our building was built in 2011 and since we moved in, we have always had problems with youths littering around the back of the building, out of sight, and minor criminal damage.
“Staff feel it has become increasingly worse, as the youths have got older and started to drive cars.
“Reception staff leave the building between 5.30pm and 6.30pm in the evening and often open the back doors to as many as 30 youths simply hanging around the back of the building, with their cars, eating, drinking and smoking.
“This leaves some staff feeling very intimidated. Police are often called, but by the time they arrive, the youths have fled.
“Footballs are kicked at the windows, whilst the cleaners are inside cleaning the rooms. It is only a matter of time before a window is smashed.
“It is very likely these are local Thrapston youths. Ironically, that means it is also very likely, the doctors and nurses here have kindly treated or will need to treat in the future members of their family.”
Anyone with information about the incidents is asked to call police on 101.
