The U.S. Treasury is taking action against another clan in the huge Japanese "yakuza" crime syndicate.

Treasury officials say the government is freezing any assets that the Inagawa-kai clan may have within the jurisdiction of the United States. By designating the clan a transnational criminal organization, the government also prohibits people in the U.S. from doing business with the group.

Treasury also is imposing sanctions on two of the group's leaders, identified as clan head Jiro Kiyota and second-in-command Kazuo Uchibori.

Inagawa-kai is the third largest of the yakuza organizations. Officials in September imposed sanctions on two others.
