The Japanese wife of a Ghanaian who died last month while he was being deported for overstaying his visa called Tuesday on police and the Immigration Bureau to disclose exactly how he died.

"I want the government to unveil the truth as soon as possible to prevent a recurrence of similar incidents," the wife of the deceased man, Abubakar Awudu Suraj, told journalists at the Foreign Correspondents' Club of Japan in Tokyo.

The FCCJ agreed not to reveal the wife's name.
