A 24-year-old man wearing a Joker costume attacked passengers on a Tokyo train line on Sunday evening. As many as 17 people were injured as they headed for Halloween parties in the city.
Witnesses say the suspect was wearing a green shirt and purple suit. He sprayed a clear liquid around the carriage and set it alight. Video footage showed passengers running through carriages away from the flames while others clambered through windows.
one witness told the Yomiuri newspaper about the attack; “I thought it was a Halloween stunt, then, I saw a man walking this way, slowly waving a long knife.” The attack happened at around 20:00 local time near Kokuryo station, in the city’s western suburbs.
Media reports say the man was arrested by police on the spot. According to news outlet Kyodo, he told police he adored the character Joker in the Batman comics.
