A 31-year-old man who is believed to have robbed a string of four banks in three different central Athens districts within the space of an hour was in police custody yesterday. The suspect is alleged to have embarked on his spree shortly before 11 a.m. with a raid on a branch of Piraeus Bank in Gyzi followed by a holdup of a branch of Citibank around the corner on Alexandras Avenue, not far from Attica’s central police headquarters. He is then believed to have carried out raids on branches of Probank and ATEbank in Kypseli and Patissia respectively. When officers eventually caught up with the masked suspect they seized two guns and a knife as well as more than 44,000 euros in loot. On questioning by police, the 31-year-old is alleged to have admitted to robbing another bank, a branch of ATEbank, in Gyzi on Monday.
