An officer on Crete has become the latest policeman to be arrested, in this case for allegedly blackmailing a wanted man to ensure the officer would not detain him. The internal affairs squad revealed yesterday that the 28-year-old officer in Iraklio was arrested after allegedly requesting a bribe of 4,000 euros from a man for whom a warrant had been issued. The policeman was taken into custody after being found in possession of the money in marked notes. It is the latest incident of alleged graft to blight the force but police sources insisted that cases are coming to light as part of efforts to root out corrupt officers. A high-ranking policeman in Patra was arrested last week for soliciting a bribe from an Albanian man to get him a Greek identity card. Earlier this month four officers were also identified as having a key role in a human-trafficking ring.
