OSAKA--A Turkish man seeking refugee status sued the government on May 29, saying Osaka immigration officers broke his right arm when they were manhandling him in a detention cell.

The 34-year-old is demanding about 4.5 million yen ($41,455) in compensation, and his lawyers say they have video proof of the “illegal violence.”

The lawyers filed the lawsuit at the Osaka District Court on May 29 and held a news conference, where they showed about four minutes of video footage captured inside an observation cell where the incident occurred.

The plaintiff arrived in Japan in January 2015 but was denied entry. He applied for refugee status, and had been held at the Osaka Regional Immigration Bureau in Osaka’s Suminoe Ward.

In July 2017, the man threw a book at a wall in the detention facility when he got annoyed by an immigration officer who was trying to confirm whether the Turkish man had taken his pain medication, according to the lawsuit.

The video shows him being hauled into the observation cell, followed by seven or eight officers in dark blue uniforms.

They forced him face-down on the floor, and he was held there by his head, torso and legs.

The lawyers said the man’s arm was broken when the officers twisted his right arm to handcuff him. Even after he was handcuffed and didn’t resist, he was held down for at least another minute.

The footage was obtained after a court ruled that the video should be preserved as evidence for a lawsuit.

The Osaka Regional Immigration Bureau declined to comment on the incident.

“We will refrain from commenting because we have not seen the lawsuit,” an official said.

The observation cell is supposed to be used for detainees who exhibit certain behavior, such as attempting to escape, but the lawyers said the room is used to punish detainees with defiant attitudes.

“A system that pays careful attention to the detainees’ rights needs to be set up,” Yoshihiro Sorano, one of the lawyers, said.
