Rod Harris, 80, of High Street, told The Hunts Post damage to the wall, which separated his front garden from a parking area at the former Collingtons Tea House, would cost thousands of pounds to be repair, as well as cost him his insurance excess and no claims bonus. Its a sturdy wall and would have taken quite a hit to knock it down, he said. I didnt hear anything and my neighbour across the street, who is normally up a bit later than me, said he hadnt heard anything. It would have taken more than five people to knock it down but it wasnt vandalism as I found a bit of plastic in the rubble which would have been part of a vehicles bumper. The speed limit is 30mph but Im sure they must have been travelling faster to cause this much damage. A Cambridgeshire police spokesman said: If you see a car which is missing part of its bumper or looks like it has crashed into a wall then give the police a call. INFORMATION: Call Cambridgeshire police on 101 if you can help.
