A member of a police riot squad died in an apparent suicide in a restroom inside the west gate guard station at the Prime Minister’s Office in Tokyo early Friday morning, investigators said.

The 25-year-old man — identified as Yuta Kurokawa — appeared to have taken his own life with the gun he was carrying, an official at the Metropolitan Police Department said.

The official said a fellow policeman — who was using the restroom at the same time — found Kurokawa bleeding from the head at around 4:40 a.m. after hearing the sound of a gunshot. He was transported to a hospital but was confirmed dead approximately 30 minutes later. Investigators said they found the weapon near the body, and that a bullet had been fired from the gun. No suicide note was found.

Kurokawa, a member of the fourth detachment of the police riot squad, had been working a night shift when the incident occurred.

Prime Minister Fumio Kishida, who has been on a weeklong tour in Africa and Singapore, was not in the office at the time.

In a previous incident in January, a 39-year-old sergeant and a member of the Metropolitan Police Department's riot squad died in an apparent suicide. He was found in a restroom inside a building in Tokyo's Nagatacho district near the Liberal Democratic Party's headquarters.

The officer's colleague found him bleeding from the head, with a gun lying on a floor nearby.
