An unexploded bomb was found yesterday outside a British car dealership in southern Athens, in the latest attack coinciding with the lead-up to the Olympic Games in August, a police spokeswoman said. The bomb was in a box under a car at a dealership for the famed Land Rover, now owned by Ford. Police detonated the device and the motive for the attack was unknown, she said. "It was a home-made explosive device of minor power," she said. Bomb squads had swept the location and declared it all clear earlier following an anonymous phone call to a newspaper saying a bomb would go off in 30 minutes. Hours later, a dealership employee spotted what he said was a suspect package behind the back wheel of a car and called the police again. It was the third attack in the capital in two weeks. **PHOTO CAPTION*** A police investigator looks for clues under a car outside a British car company after they found a small bomb which police blew up in a suburb of Athens.
