STILLWATER, Oklahoma - Charges have been filed against the former member of the OSU FarmHouse fraternity, accused of sexually assaulting other members.

Nathan Michael Cochran, 22, is facing three charges of sexually battery for the alleged incidents.

Officials at Oklahoma State University launched an investigation on Nov. 12, 2012, but say federal law prohibited them from telling Stillwater Police until last Friday.

Stillwater Police say they have interviewed the alleged victims, however they believe there could be more.

An OSU newspaper reported the allegations of sexual assault against the former FarmHouse member. The O'Collegian reported about receiving an anonymous email claiming Cochran committed more than 10 assaults on fraternity pledges.

Gary Shutt, Director of Communications at OSU, says that an investigation had been completed by a student conduct group on Nov. 30, 2012. The students decided not to notify police at that time, Shutt reportedly told The O'Collegian.

Multiple agencies have been involved with this investigation.
