At least 15 people have been killed after a knife-wielding man went on a rampage at a facility for the handicapped, Tokyo police reported.
At least 45 people are believed to have been injured in the attack that began at about 2:30 a.m. Tuesday, the NHK news agency reported.
An employee of the Tsukui Yamayuri-en center phoned police to say a man with a knife had broken into the building.
The man surrendered at a police station about two hours later. He said he was a former employee of the center, NHK reported.
The man shouted, "I want to get rid of the disabled from this world," police reported, according Asahi Shumbun.
The 26-year-old suspect left the knife in his car when he entered the police station, the Associated Press reported. He was arrested on suspicion of murder and trespassing charges.
