A former gang member who was arrested for wounding four people during a stabbing rampage outside Toyocho subway station in Tokyo's Koto Ward on Tuesday morning, was quoted by police as saying that he received ultrasonic sound waves in his body telling him to stab people.
The suspect, identified as Tamotsu Kawamura, 49, is a former gang member, police said. He was arrested once before in 2005 for stabbing a man in a pachinko parlor. He lives near Toyocho station.
In Tuesday's rampage, witnesses said Kawamura was yelling unintelligibly as he stabbed four passersby near the exit to the station which is on the Tozai line, at about 8 a.m. The four victims -- all men ranging in age from their 30s to 60s -- were taken to hospital where they are in a stable condition.
NHK reported that Kawamura, who had two knives, was restrained by some commuters and station staff until police arrived. He was seen being led away by about 10 police officers.© Japan Today
