On the evening of October 31, local time, a number of fire trucks, ambulances and police cars gathered outside the Keio Line Kokuen Train Station in Chofu City, Tokyo, because of a serious and vicious injury incident, it is reported that 17 people have been injured, one of whom is estimated to be between the ages of 60 and 70, who is seriously injured and is still unconscious. Some of the injured were knife wounds, while others suffered physical damage caused by inhalation of smoke.
After receiving the alarm, the Japanese police took control of the situation in the carriage, and the arrest was a 24-year-old man who claimed to be Hattori Kyota, but the address and occupation were not yet clear. The police found a knife about 30 centimeters long from him, and Hattori did not resist the arrest, confessed to his crime, and also admitted: "I want to kill people and was sentenced to death." I thought of the Oda Kyu line thing...". Hattori's reference to the Odakyu Line refers to a man wielding a knife on a train on the Tokyo Odakyu Line in August this year, injuring 10 passengers, including those who were seriously injured.
Before the police surrounded him, Hattori smoked calmly, as if what had happened had nothing to do with him. Judging from the way Hattori was dressed at the time of the crime, he dressed himself up as the villain of Marvel Comics, the "Joker". October 31 is the traditional festival halloween in Europe and the United States, and young people in Japan also like it, so Hattori's strange dress that night did not attract much attention, in fact, many people took the train to Shinjuku that night to go out, just to go to parties and so on.
According to a passenger description afterwards, "a man in his 20s wielded a knife and was holding a liquid that appeared to contain sulfuric acid in his hand and threw it on others", and some passengers said they saw blood on the knife. Others said the man poured oil into the carriage and set it on fire, and some of the seats were quickly burned down, which was why some of the injured inhaled smoke.
At the time of the incident, the tram just arrived at the station, but the safety gate was not opened, and many passengers climbed out of the tram window and jumped over the gate to escape.
Although Hattori claimed to have "wanted to obtain the death penalty by killing," the real motive is still under investigation.
