An Athens policeman serving in the department of illegal immigration has been arrested for selling thousands of euros in forged notes and half a kilo of cocaine to an undercover colleague, police said yesterday. The 27-year-old policeman, who was not named, is believed to have been one of the top figures in an international gang that smuggled drugs and counterfeit notes into Greece while also sexually exploiting illegal immigrants who were made to work as prostitutes. He was arrested on Tuesday in Aghia Paraskevi Square in northeastern Athens, along with two alleged accomplices – a Greek man and a Moldovan woman – taking 22,000 euros in return for 500 grams of cocaine. The undercover policeman who arranged the deal had also agreed to buy 8,000 euros in forged banknotes printed in Bulgaria. Police proceeded to arrest another seven suspects, including an Albanian and a Belorussian. Officers also found five Eastern European women in a Syngrou Avenue hotel, who had been forced by the gang into prostitution.
