University of Arizona Police Investigate Alleged Fraternity Sexual Assault with Strangulation Sign

The University of Arizona Police Department is investigating an alleged sexual assault involving a sorority member at the Sigma Phi Epsilon fraternity house on August 26, 2026, where the victim reported difficulty swallowing, which investigators noted as a "possible sign of strangulation"[1][3][7][10]. No charges have been filed, and no arrests have been publicly announced as of October 21, 2026[3][6][7].

This investigation comes as the University of Arizona's Greek life system faces intense scrutiny, with all 21 Interfraternity Council chapters recently suspended due to widespread allegations of misconduct, including hazing and assault[4][11]. The incident highlights ongoing safety concerns within the university's fraternities.

Investigation Details

Search warrant records state the victim reported consensually kissing one man at the Sigma Phi Epsilon house but did not recall agreeing to sex[1][2]. She woke up without her pants and underwear[3]. The victim reported drinking multiple tequila beverages that night[2][3]. During a recorded phone call, one alleged perpetrator admitted to having sex with her, claiming it was consensual, and denied a second man was involved, stating he was drunk and "fuzzy" on what happened[2][3]. The University of Arizona Police Department (UAPD) is actively investigating the report[1][5]. The Pima County Attorney's Office stated the case has not been referred to it for prosecution[3].

Broader Context for Fraternities

This alleged assault occurred while Sigma Phi Epsilon was already on probation until May 2027 due to previous hazing allegations from Fall 2025[8][9]. These earlier allegations included sleep deprivation, forced alcohol consumption, kidnapping, calisthenics, and illegal drug use[9]. Separately, in early October 2026, the University of Arizona Dean of Students suspended activities for all 21 Interfraternity Council chapters due to various misconduct allegations across nearly half of them, including hazing, physical assault, and drug and alcohol abuse[4][11]. Some suspensions have since been lifted after mandatory meetings with the dean[3].
