31 October 2021: Tokyo, Japan

Seventeen people were injured — one of those stabbed — when a man dressed as the character “The Joker” from the movie Batman, entered a train and began lashing out with a knife the night of October 31. It happened on the Keio Line train in Tokyo. A 70-year-old man was reported in critical condition after he was stabbed in the chest. The perpetrator also sprayed lighter fluid around the train car and lit it on fire. Some passengers pulled the emergency stop and escaped through the windows. A 24-year-old man self-identified as Kyota Hattori was arrested at the scene. He told authorities, “He wanted to kill people and be given the death penalty,” according to the Tokyo Police. He is shown here calmly smoking a cigarette after the attack, before the authorities arrived.
