A fraternity at
Alpha Delta Phi has been suspended while Durham, N.C., police investigate what happened at an off-campus house leased by fraternity members.
"Duke University is cooperating with the Durham Police Department in the investigation of an alleged sexual assault of a Duke student at an off-campus private residence that is leased to members of the Alpha Delta Phi fraternity," the school said in a statement emailed to reporters.
"Pursuant to Duke's policy, the fraternity has been placed on interim suspension until further notice. As this case is now being actively investigated by the Durham Police Department, Duke will not have any further comment at this time."
Durham Police Chief Jose Lopez told WRAL-TV that his department is seeking information from anyone at the Jan. 8 party.
No charges have been filed.
Local news outlets obtained a search warrant that says the woman told police she had drinks at the party before waking up the next day in only a T-shirt. The warrant says the last thing she remembers was dancing with friends.
The warrant reportedly says investigators took a mattress, comforter and condom from the house.
