A bank robbery in Thessaloniki resulted in an innocent bystander being shot after police stumbled across the holdup, prompting a street shootout and car chase, authorities said yesterday. The heist took place at around midday when two armed men entered a branch of Piraeus Bank. After completing the robbery, the assailants were spotted leaving the bank by two officers driving past in a patrol car. Authorities said a shootout followed, resulting in the minor injury of a 31-year-old man who was nearby. A car chase through Thessaloniki then took place before police managed to stop the assailants, aged 20 and 25, and arrest them. Authorities found in their possession two guns, a Kalashnikov rifle, a submachine gun and the cash taken from the bank.
