Explosives experts yesterday destroyed a small time bomb that had been placed outside a British car dealership in southern Athens, in what police described as a deliberate attempt to make a laughing stock of the force. The discovery of the device followed a couple of warning phone calls made to the media, with a gap of 13 hours between the two calls. The first call, around 12.35 a.m., said a bomb had been planted outside the Rover dealership, on the junction of Vouliagmenis Avenue and Thrakis Street in Hellenikon. Police rushed to the spot, but a two-hour search failed to uncover any explosives. A second call was made at around 1.30 p.m., and that time officers found the bomb in clear view under a car outside the dealership. The device consisted of a small quantity of dynamite, a detonator and a timer placed in a tin. Police, who see the attack as a stunt to make the force look silly, said the device had definitely not been there during the first alarm, adding that it bore no resemblance to the bombs that went off outside the Kallithea police station on May 5.
