The police officer who shot and wounded a cafe owner in Athens’s historical district of Plaka on Friday had just returned to duty after extended leave for psychological reasons and was being investigated in connection with financial fraud, it was revealed yesterday. The 48-year-old officer, who has not been named, is due to appear before a magistrate today, as his victim continues to recover from a non-life threatening injury. Sources said the policeman, who was in charge of the Kypseli police station, had been off duty since October when he asked to take a break because of psychological problems. He returned to the force on March 12, one day before he shot the cafe owner. The officer handed himself in several hours after the shooting. The police’s organized crime squad had also investigated the officer in connection with a case of fraud in Oropos, north of Athens. His victim was also probed as part of the same investigation.
