Cuma Yasar, 40, made the statement in an attempt to persuade an Istanbul court not to place him in detention."I caught the plane at the last moment. It's why I could not take my medication. I don't remember what happened on the plane. I lost consciousness. When I came to, I was at the police station," he said.Yasar was heard by judges at the Bakirkoy court on the European side of the city and was then taken to a nearby institution where he was to have psychiatric tests, the agency said.If the tests show that Yasar is sane he is likely to be charged and faces 10 years in prison.He tried on Wednesday to hijack a Turkish Airlines Boeing 737, which had 59 passengers on board, as it was less than one hour from Istanbul.A fellow passenger said he yelled in Turkish that he had a bomb and demanded the plane return to Oslo.The hijacker reportedly headed for the cockpit before being overpowered by other passengers.He was arrested when the plane arrived in Istanbul unscathed, and police said no explosives were found on board.A Norwegian daily said Thursday, quoting a friend of the hijacker, that Oslo repeatedly denied asylum to Yasar.A spokeswoman for the Norwegian Immigration service told AFP she could not comment on the matter because of a confidentiality policy.
