BLOOMINGTON – About two-thirds of an Indiana University fraternity’s members have been kicked out after an investigation into hazing and alcohol violations.

The national headquarters of the Alpha Tau Omega fraternity said it is allowing fewer than 20 of 126 active members to remain in IU’s century-old chapter. Some can appeal their expulsions.

The fraternity was already on alcohol violation probation when university officials asked that the national office investigate the chapter.

National fraternity CEO Wynn Smiley said that IU chapter members denied knowing about hazing rituals and didn’t acknowledge a low chapter grade-point average.

He said some members had an attitude that the fraternity’s purpose was to be "party central."
