A man has died after being stabbed in the neck on a bullet train in Japan.
News reports said two women who appeared to be in their twenties were also wounded but their injuries were not life-threatening.
Police said they arrested Ichiro Kojima, 22, after the train made an unscheduled stop today at Odawara station, west of Tokyo, following an emergency call that there was a knife-wielding man.
He attacked the victims around 10pm aboard the shinkansen train which was travelling from Tokyo to a station in Osaka, police and news reports said.
Police officers stormed into the rail carriage and took the man into custody after the train, carrying some 880 passengers, made an emergency stop at Odawara station.
Police arrested the 22-year-old unemployed suspect on suspicion of attempted murder, a local police spokesman said.
‘A male passenger was sent to hospital and his death was confirmed later,â the spokesman said.
The suspect told investigators that he felt ‘frustrated and wanted to kill someoneâ, public broadcaster NHK said, adding that he used at least two knives.
Witnesses said passengers fled in panic, some of them in tears.
‘All of a sudden, a lot of passengers were dashing from behind. People panickedâ, a 44-year-old male passenger said.
‘Everyone appeared to be feeling the strain and some of them cried,â he said.
Another passenger said : ‘Everyone fled and fell like one domino falling after another. I was scared to death.â
Japan has one of the lowest rates of violent crime in the developed world and mass attacks are extremely rare.
In 2015, a man set himself ablaze on board a moving bullet train, killing himself and a woman in an unprecedented incident.
