A young couple who allegedly used a toy pistol to carry out a series of robberies in the northern city since October last year have been arrested, police in Thessaloniki said yesterday. A 31-year-old mother of a 3-year-old child, identified as S.M., and a 37-year-old man identified as T.Z., were arrested in their home in possession of small quantities of drugs, precision scales, two air guns and 2,000 euros. The two allegedly got away with a total of 55,000 euros after robbing one National Bank and three Nova Bank branches, and an attempted robbery at an Agricultural Bank branch. They had reportedly used the money to buy cars and clothes. Police were able to identify the pair from closed-circuit security cameras at the bank. They had made no attempt to disguise themselves other than wearing caps.
