At least 15 people have been killed and up to 45 injured by a knife-wielding man at a facility for the disabled in Japan, Japanese media reported.
Police in Sagamihara in Kanagawa Prefecture, about 40 kilometres south-west of Tokyo, have arrested a man in his 20s who told police he was a former employee of the centre, Kyodo said.
Japanese media said staff called police at 2:30am local time on Tuesday with reports of a man armed with a knife on the grounds of the sprawling Tsukui Yamayuri Garden facility.
A man handed himself over at a police station half an hour later and said: "I did it", a spokesman at Kanagawa Prefecture Police said.
Asahi Shimbun reported that the suspect was quoted by police as saying, "I want to get rid of the disabled from this world".
"We are still confirming details of the case," the police spokesman added.
