A man brandishing a knife on a Tokyo commuter train on Sunday stabbed several passengers before starting a fire, which sent people scrambling to escape and jumping from windows, police and witnesses said.
The Tokyo Fire Department said 17 passengers were injured, including three seriously.
The attacker, identified as a man in his 20s, was arrested on the spot and was being investigated on suspicion of attempted murder, public broadcaster NHK said. His motive was not immediately known.
Nippon Television reported that the suspect told police he used an earlier train stabbing case as an example.
NHK said witnesses told police that the attacker was wearing a bright outfit — a green shirt, a blue suit and a purple coat — and looked like a comic book character or someone going to a Halloween event.
Tokyo police officials said the attack happened inside the Keio train, near the Kokuryo station.
Television footage showed a number of firefighters, police officials and paramedics rescuing the passengers, many of whom escaped through train windows. In one video, passengers were running from another car, where flames were gushing.
‘It was horrifying,’ witness says
NHK said the suspect, after stabbing passengers, poured a liquid resembling oil and set fire, which partially burned seats.
Shunsuke Kimura, who filmed the video, told NHK that he saw passengers desperately running, and while he was trying to figure out what happened, he heard an explosive noise and saw smoke wafting. He also jumped from a window but fell on the platform and hurt his shoulder.
“Train doors were closed and we had no idea what was happening, and we jumped from the windows,” Kimura said. “It was horrifying.”
The attack was the second involving a knife on a Tokyo train in two months.
In August, the day before the Tokyo Olympics closing ceremony, a 36-year-old man stabbed 10 passengers on a commuter train in Tokyo in a random burst of violence. The suspect later told police that he wanted to attack women who looked happy.
