A Turkish man today hijacked a commercial passenger plane flying from the southeastern city of Diyarbakir but then gave himself up to the authorities, an Ankara airport official said.
"The hijacker has surrendered," the official said, on condition of anonymity.
Police believe the hijacker acted from personal, not political motives, and may be mentally ill, the official added.
The state-run Anatolian news agency identified him as an unemployed man from Diyarbakir with a drug-related criminal record. CNN Turk television said he was believed to have taken drugs before boarding the flight.
"When he got up he said he had a bomb and he wanted to go to Iran," passenger Firat Keles told CNN Turk of the hijacker, who was aged about 40.
The Pegasus Airlines plane had been carrying 178 passengers from the southeast city of Diyarbakir to Istanbul.
Special forces boarded the plane at Ankara airport to check whether the man had any accomplices before allowing passengers to disembark, the airport official said.
