A Brazilian man has sued the Japanese government after sustaining injuries in October last year while being forcibly restrained at an immigration facility in Tokyo, people familiar with the matter said Monday.

Andre Kussunoki, 33, has filed a lawsuit with the Tokyo District Court, claiming the physical restraint used by immigration officials was unnecessary and amounted to assault. He is demanding that the state pay ¥5 million in damages.

Kussunoki says he still suffers from pain and cannot raise his arm. He sustained injuries to his shoulder when he was restrained by several officials after refusing to follow an order at the Tokyo Regional Immigration Bureau, the sources said. The bureau detains foreign nationals who have received deportation orders.
