The essentials
A teen's lawsuit alleges a February 2026 sexual assault at a University of Chicago fraternity house; police are investigating.
A teenager has filed a lawsuit against Alpha Delta Phi and its University of Chicago chapter, alleging she was sexually assaulted at the chapter house on February 7, 2026. The lawsuit alleges a member gave her a shot of an unidentified alcohol, then led her to an upstairs bedroom, where he assaulted her while she was unable to refuse.
The plaintiff reported the alleged assault to the Chicago Police Department, and the investigation is ongoing. The lawsuit also references two sexual assault reports from 2009 and an anonymous 2022 social media post alleging assault at the same chapter house. These are allegations, and none have been adjudicated.
The lawsuit further alleges that the national organization received additional misconduct reports before February 2026 but did not impose an interim suspension or event safeguards on the chapter. Alpha Delta Phi National says it suspended the member involved, is aware of the allegations, and will cooperate with law enforcement. The plaintiff seeks damages for physical injuries, emotional distress, and psychological harm. Separately, a sexual assault allegation was reported at another fraternity near the University of Chicago campus.

Chicago police are still investigating, and no findings have been announced in the available material.
National group says it suspended member and will cooperate with authorities
