A civil lawsuit filed in New York alleges that seven Cornell University fraternity brothers sexually assaulted a female student at their Chi Phi house on 19 October 2024. According to the complaint, the woman arrived already intoxicated, was given more alcohol and drugs including ketamine, and was then taken to a room where she was allegedly raped repeatedly over approximately four hours by multiple assailants who communicated via Snapchat to summon additional fraternity members. The university is also being sued for allegedly failing to protect students despite knowing of risks within its Greek system.

The alleged victim reported the incident to campus police on 8 November 2024 after encouragement from friends. Cornell temporarily suspended the fraternity and the seven students, then conducted an investigation spanning at least 12 hearings in May 2025; the investigation's findings and any disciplinary action remain undisclosed. The Tompkins County District Attorney confirmed that criminal investigation did not result in charges against any of the seven men. One defendant's attorney denies all allegations and states law enforcement has had no contact with his client or found probable cause. The plaintiff claims the alleged ordeal forced her to leave Cornell and caused significant psychological harm.
