A shipowner shot in the neck on Thursday night outside his northern Athens house was unable yesterday to provide police investigating the attack with any tangible leads, sources close to the investigation said. Nikos Mazarakis, 61, was being nursed at the Athens Erythros Stavros hospital and was out of danger. He was well enough to testify regarding the Anixi shooting, but could only offer robbery as a possible motive for the attack. Mazarakis was shot once, with a small-caliber bullet, by a man riding pillion on a motorbike. The gunman and his accomplice were both wearing crash helmets. Police believe the attack, which came just after Mazarakis parked his car outside his house on Gortynias Street, was a contract hit rather than an attempt to scare the shipowner, who was lucky to escape with his life. Detectives are now scrutinizing Mazarakis’s business dealings and family affairs for a lead on the shooting. A terrorism link is considered highly unlikely.
