Con artists have often tried to pass themselves off as police officers, plumbers and electricians to talk their way into the homes of pensioners, but two men arrested in Thessaloniki yesterday added a new scam to the list by pretending they were cardiologists. The suspects, aged 52 and 70, allegedly entered several homes belonging to women over the age of 80 in the Toumba area of the northern port city between May 3 and 9. Police said that the pair offered medical advice to the women and then convinced them to part with between 1,000 and 1,800 euros for a case of medical items. After opening the cases after the men had left, the victims found only several cheap objects inside. Police have accused the men of serial fraud and are examining the possibility that they conducted the same scam in other parts of Greece.
