NHK has learned that a man arrested for theft fled a police hospital in Tokyo, where he was being treated for fractured bones.
The man, who is a South Korean national in his 60s, was found to be missing from the hospital in Nakano Ward at about 7 a.m. on Sunday.
Tokyo Metropolitan Police say that he disappeared after he went to the toilet on the fifth floor of the hospital.
The police say one of the two police officers who were posted at the hospital was on watch outside the restroom.
Earlier this month, he was arrested on suspicion of theft.
He tried to evade police and was injured when he jumped from a building. He was temporarily released for treatment.
Police say he is still at large.
