It appears an employee of AV(2010)PLC ( who is on the redundancy list), decided to take the sort of action, at Kidderminster, that the management of AV should have organised years ago. (Perhaps they didn't have the balls.... Matt)
The chap in question, built up a stockpile of 50+ trolleys recovered from the nearby Cut and loaded them onto a tipper truck. In the early hours of Saturday morning he backed the truck up to the front doors of the offending store and dumped the lot!
Staff arriving at the store shortly before opening time were faced with a tangled mass of smelly, mangled, trolleys blocking the entrance. The store lost several hours trading as a result and the store manager was said to be furious.
A local boater photographed the proceedings, but confessed he thought his pictures might have suffered from camera shake. "I was laughing so much", he said "I should have used a tripod".
