Three people were injured yesterday after two bank robbers opened fire in a busy street in central Thessaloniki when their getaway motorcycle failed to start. The would-be robbers, two Georgians aged 30 and 39, entered a branch of Piraeus Bank holding guns and one wielding a hand grenade, according to witnesses. Upon leaving the bank with their loot, the pair could not get their motorcycle started and so tried to threaten passing motorists into stopping with the aim of hijacking their vehicles. After several failed attempts, passers-by realized what was happening and tried to disarm the robbers, who fired their guns a total of six times. Two people were injured in the hail of bullets, both in the legs, and a third sustained head injuries after being hit by the butt of one of the guns. An off-duty officer in the area at the time alerted police, who sent two patrol cars to the scene and arrested the pair. Officers said the Georgians have been charged with theft in the past.
