The University of Iowa police said they received a third-party report Tuesday that a female student was sexually assaulted on campus.

According to a press release, the report said the alleged assault happened at Daum Residence Hall the weekend of Aug. 20-21.

That makes it at least the fourth alleged sexual assault or attempted sexual assault since October 2010, including alleged incidents reported at the Finkbine driving range, Stanley Hall, and on the Pentacrest.

Charles Green, the assistant vice president for the UI police, had no further information Wednesday afternoon. Officials are not permitted to begin investigating a sexual assault until it is reported by the alleged victim, but the Campus Security Act mandates the university issue a timely warning.

The UI police recommend students walk in groups when possible and use transportation services such as the Cambus and Nite Ride.
