German police are searching for the man they say could be the most stupid burglar they have ever encountered. The unknown man broke into the building of a lumber sales company in Bremen during the night and violently assaulted a coffee machine which contained only tokens, despite a sign on the door explaining it did not take cash. He then went on to steal a mobile phone, which only works in the grounds of the company, and a cordless screwdriver - but forgot the batteries and charger. Finally, police say the intruder drank a can of coke -- 12 months past its sell-by date -- that had been standing in one of the offices. A police spokesperson said that the authorities are looking for a man “stranded with a load of useless junk, looks tired, is sick to his stomach and is probably the laughing stock of all his mates.”
