TUCSON, AZ — The University of Arizona is investigating a fourth fraternity this month after new allegations of hazing surfaced involving Sigma Phi Epsilon.
The Dean of Students Office sent a letter to the fraternity's president late last week notifying the chapter it was under investigation for allegedly violating the student code of conduct and endangering members of the university community.
The investigation stems from a report filed April 28 alleging that Sigma Phi Epsilon subjected pledges to hazing during the fall 2025 semester.
According to university officials, the alleged conduct included sleep deprivation, kidnapping, forced physical exercise and making new members consume alcohol.
The report also referenced illegal drug use by fraternity members.
University officials said the alleged behavior violates multiple provisions of the Arizona Board of Regents Student Code of Conduct, including rules related to alcohol, drugs, hazing and conduct that endangers the health or safety of others.
Sigma Phi Epsilon has been placed on an activities suspension while the investigation is ongoing. Under the terms of that suspension, the chapter cannot host, attend, sponsor or participate in any organizational events. Only internal business meetings are permitted.
The fraternity is also barred from any contact with new members, officials said.
The action against Sigma Phi Epsilon is the latest in a string of disciplinary moves targeting Greek organizations at the university.
Sigma Alpha Mu and Sigma Chi were both placed on interim loss of recognition following separate reports involving hospitalizations and severe hazing. Sigma Alpha Mu faced additional allegations involving burns caused by hot liquids. Phi Delta Theta was placed on activities suspension earlier in the week over allegations of forced alcohol consumption and humiliation of new members.
According to the University, the Sigma Phi Epsilon president was asked to contact the Dean of Students Office this week to discuss the allegations.
