Japanese police have arrested a man who stabbed 10 passengers on a commuter train in Tokyo.
The 36-year-old man, identified by police as Yusuke Tsushima, told officers he wanted to kill women who appeared happy and chose his targets at random, public broadcaster NHK said.
The attack took place Friday night around 8.30pm local time near Seijogakuen station, in the capital's Setagaya Ward.
The station is only a few miles away from the Tokyo 2020 Olympic stadium, where sporting events will conclude on Sunday.
The initial victim, a woman in her 20s, was in serious condition, according to NHK and other Japanese media.
The Tokyo Fire Department said nine of the 10 wounded passengers were taken to nearby hospitals, while the 10th was able to walk away.
All of the injured were conscious, fire department officials said.
NHK said the suspect left his knife behind as he fled the scene, and later walked into a convenience store and identified himself as the man on the news, and said he was tired of running away.
The store manager then called the police after identifying bloodstains on the man’s shirt.
According to TBS television, the suspect told police he developed the intent to kill women who “looked happy”, and stabbed a woman who happened to be seated near him in the carriage.
He also told police that he chose to stage the attack inside a train because it offered the chance to kill a large number of people.
The suspect was also carrying cooking oil and a lighter, with which he allegedly planned to set a fire inside the carriage.
A witness at a nearby station where the train halted said he saw panicked passengers bolt out the carriages.
