A 24-year-old man dressed in Batman’s Joker costume attacked passengers on a Tokyo train line on Sunday evening, injuring 17 people as many party-goers headed into the city centre for Halloween gatherings, media reported.
Police arrested the suspected attacker on the spot, media reported. A man believed to be in his 60s was unconscious and in critical condition after being stabbed, while witnesses also said the attacker had spread fluid around the train and started a fire, according to media.
One video uploaded on Twitter showed a steady stream of people running away from a train car where, seconds later, a blaze lit up.
