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.
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. Another video showed passengers rushing to squeeze out of the train’s windows and onto the platform where the train had made an emergency stop.
“I thought it was a Halloween stunt,” one witness told the Yomiuri newspaper, recalling the moment he saw other passengers running in a panic towards his train car. “Then, I saw a man walking this way, slowly waving a long knife.” There was blood on the knife, he said.
