A man has stabbed at least 10 passengers on a commuter train in Tokyo, seriously injuring two people. The suspect left a knife behind as he fled, and was arrested later on Friday in the Japanese capital, according to NHK public television. Tokyo is hosting the Olympics, which end on Sunday. The city’s fire department said nine of the 10 passengers were taken to nearby hospitals, while the 10th was able to walk away. All of the injured were conscious, fire department officials said. A witness said passengers were panicking and rushing out of the carriages. Another witness told NHK he saw passengers smeared with blood coming out of the train, as an announcer asked for doctors and passengers carrying towels. Dozens of paramedics and police arrived at the station, one of the witnesses said. NHK reported that the suspect walked into a convenience store and said he was tired of running away, and the store manager called police after seeing bloodstains on the man’s shirt. It said the suspect was in his 20s. The stabbing occurred near Seijogakuen-Mae station, according to the railway operator, Odakyu Electric Railway Company. The line is mostly above ground but runs underground in the area where the attack happened. Police declined to comment and no other details were immediately available. Japan has had a series of high-profile killings with knives in recent years. In 2019, a man carrying two knives attacked a group of schoolgirls waiting at a bus stop just outside Tokyo, killing two people and injuring 17 before killing himself. In 2018, a man killed a passenger and injured two others in a knife attack on a bullet train. In 2016, a former employee at a home for disabled people killed 19 people and injured more than 20.
