Moment of arrest of the Joker knifeman identified as Kyota Hattori

The attacker was identified as 24-year-old Kyota Hattori.
While three were critically injured, authorities said not all of them were stabbed and most of the injuries were not serious.
Investigating authorities later reported that he told them he wanted to kill people and get the death penalty.
Nippon Television said he used an earlier train stabbing case as inspiration for carrying out the crime.
According to NPR, this is the second knife-involving incident on a Tokyo train in the past three months.
