ST. PAUL, Minn. (AP) -- Prosecutors in Minnesota have charged four suspects in
an alleged sex-trafficking ring that targeted women who are Chinese nationals
and kept them isolated.

Washington County Attorney Pete Orput said Wednesday the ring operated out of
Irvine, California, but involved criminal activity in North Dakota and
Minnesota, mainly in the eastern Twin Cities area.

Charges include sex trafficking, promoting prostitution and concealing criminal
proceeds.

The only Minnesotan charged in the case is 28-year-old Dongzhou Jiang of
Blaine. Orput says he acted as a ``regional boss,'' taking the women to various
sites around the Twin Cities where they were forced to have sex with men.

Prosecutors say the women were forced to work 12 to 14 hours a day.

The three California defendants, all women await extradition to Minnesota.
