Friday's apparent suicide of an Indian man held at the East Japan Immigration Control Center in Ushiku, Ibaraki Prefecture, has prompted dozens of detainees at the facility to stage a hunger strike in protest, according to volunteers supporting the detainees.

According to Mitsuru Miyasako, director of the Provisional Release Association in Japan, about 130 detainees had participated in the protest as of Tuesday.

He said he obtained the information from detainees he interviewed at the center.
