The University of Arizona has suspended all activities of its Sigma Phi Epsilon fraternity chapter after a female student reported being sexually assaulted by two men inside the organization’s Tucson house in August.

Severe Restrictions Enacted Following Police Disclosures

Campus administrators issued the immediate sanction after local television station KOLD-TV in Tucson publicized search warrant records dated September 9. The documents outlined harrowing details from the student, who told investigators that she attended the fraternity house on the night of August 26, drank alcohol, and consensually kissed an individual. She subsequently woke up to find two men sexually assaulting her in the residence.

According to the police records, the victim recalled feeling one assailant’s breath against her face and experienced severe difficulty swallowing the following morning, which authorities attributed to possible strangulation. The student reported the assault to law enforcement the day after it occurred, undergoing a comprehensive forensic examination at a nearby hospital while providing investigators with detailed physical descriptions of both attackers.

"It has been determined that your organiaation presents a substantial risk to members of the university community," said Associate Dean of Students Whitney Mohr in a letter sent to the fraternity on Wednesday.

Under the conditions of the suspension outlined in Dean Mohr’s directive, the Sigma Phi Epsilon chapter is barred from hosting, participating in, sponsoring, or attending any organizational events until the investigation concludes. The administrative decree strictly forbids fraternity members from approaching or contacting the victim and her relatives, warning that any attempts at retribution or intimidation will provoke immediate escalation and additional punitive measures.

Pattern of Disciplinary Violations and Administrative Crackdown

The grave criminal complaint arrives at a time when the chapter was already operating under disciplinary probation. University officials had placed Sigma Phi Epsilon under conditional warnings and assessed financial penalties just months earlier in July in response to hazing violations. Furthermore, Dean Mohr’s letter formally accused the chapter of distributing alcohol to underage individuals on two separate dates: August 26, the night of the reported assault, and again on September 29.

The Tucson campus has faced severe pressure regarding Greek-life safety standards and institutional oversight. Earlier in October, university administrators instituted an expansive intervention, freezing operations for 21 separate fraternities amid widespread reports involving physical assault, dangerous hazing rituals, and illicit drug and alcohol conduct. While most organizations regained standing, five fraternities remain officially sidelined under active administrative penalties.

Investigation and Corporate Fraternity Response

Following the public exposure of the criminal investigation, the national leadership of Sigma Phi Epsilon addressed the incident. National Chief Executive Officer Brian Warren issued a formal statement affirming that the organization maintains zero tolerance for sexual assault or misconduct. Warren confirmed that the national office had instructed all members of the Arizona chapter to cooperate fully with investigators and had suspended individuals connected to the case, though the national headquarters did not disclose the identities or specific organizational roles of those suspended.

Representatives from the local Tucson chapter failed to respond to media requests, inquiries, and emails following the disciplinary action. Meanwhile, the University of Arizona Police Department confirmed that detectives continue to actively pursue leads tied to the September search warrant. The Pima County Attorney’s Office stated on Tuesday that local law enforcement had not yet formally referred the criminal file to prosecutors for potential indictment, leaving the campus community watching closely as institutional accountability and criminal justice processes unfold.
