GRAND FORKS (AP) - The University of North Dakota has put the Gamma Phi Beta sorority on probation for a year.

The action comes in the wake of a sorority party where students wore mock American Indian clothing and red face and body paint. The party last November led to discrimination complaints from Indian students. The sorority president later apologized.

The yearlong conduct probation imposed by the school's dean of students office means the sorority can participate in university events and host parties but will be suspended if it violates the school's Code of Student Life again.

The sorority also is required to design a diversity education program for its members.

Associate Dean of Students Cara Goodin says similar sanctions have been taken against the sorority by its parent organization, Gamma Phi Beta International.
