A Japanese woman submitted a criminal complaint Monday demanding that prosecutors in Chiba Prefecture take action against the immigration officers at Narita airport who in March overpowered her Ghanaian husband to get him on a jet, where he subsequently died of unknown causes while handcuffed in his seat.

The woman, who asked not to be named, took the legal action because Chiba police have not arrested or turned over to prosecutors the immigration officers allegedly involved in the death of deportee Abubakar Awudu Suraj, even though three months have passed.

"The Immigration Bureau and police have not explained what really happened," said Mayumi Yoshida, assistant general secretary of Asian People's Friendship Society and a supporter of the widow.
