Investigators Monday searched the home of a man who fatally stabbed a police officer in Setagaya Ward on Sunday before dying of a gunshot wound suffered in the struggle, Metropolitan Police Department sources said.
The assailant, identified as Yoshihiko Toyama, 54, a resident of the ward, was shot by Assistant Inspector Takashi Hirata during the attack and died soon after.
Hirata, 51, was posthumously promoted two ranks Monday to superintendent.
