Coverage of a police report describes a reported sexual assault at the AEPi house on October 11, 2026. Friends reportedly found the complainant with a partially undressed man in a bathroom; people outside allegedly cheered or obstructed access. Those details are allegations in the reported account, not findings against identified individuals. WBEZ reported no arrests and ABC7 reported no charges in the cited coverage. No accused fraternity member is publicly named in those sources and no civil lawsuit concerning this incident was verified. The investigation is separate from reporting about a February 2026 Alpha Delta Phi incident. The official AEPi chapter roll lists the University of Chicago chapter as Lambda.
