A 21-year-old woman alleges that she was sexually assaulted early Sunday morning at a fraternity house near the University of Chicago campus. Chicago police say the woman reported the incident. Multiple outlets identify it as occurring during a party at a fraternity residence in the Hyde Park area.

The reporting varies in detail, including references to the suspect fleeing the building and the specific fraternity chapter involved. Block Club Chicago reports that the fraternity has been asked not to hold events while the investigation is ongoing. The sources do not agree on all investigative specifics beyond the allegation, the reported time frame, and the general location near the university.

Authorities have not publicly established further facts such as the suspect’s identity or charges at the time of these reports. The case remains under investigation.
