A 19-year-old man has been arrested and a 20-year-old is being sought on suspicion of blackmailing a teenage girl by threatening to post nude photographs of her on a fake profile they had set up on social networking site Facebook. According to the police, the 19-year-old Greek and his 20-year-old Albanian friend posted a nude picture of the girl on Facebook. The pair contacted the 19-year-old student via the MSN instant messenger service and informed her they would post more indecent pictures of her unless she sent them other revealing photographs. The teenager went to the police’s electronic crimes squad, who digitally traced the two men. They discovered the Facebook page had been constructed from the 19-year-old suspect’s home in Piraeus.
