Three University of Arizona fraternities are being investigated after several allegations surrounding extreme hazing and student hospitalizations have surfaced, with campus authorities insisting the organizations pose a “substantial risk” to members of the school’s community. 

Sigma Alpha Mu, Sigma Chi and Phi Delta Theta are all facing some level of disciplinary action stemming from allegations of hazing, according to letters sent by the dean of students and obtained by Fox News Digital.

The school’s Sigma Alpha Mu fraternity has been placed on an “interim loss of recognition,” making it one of two campus organizations not permitted to use campus facilities for events until the investigation is completed. 

The move comes amid allegations from new members that they “experienced burns from hot liquids, forced consumption of alcohol, alcohol poisoning and blackouts, resulting in the hospitalization of Sigma Alpha Mu members,” according to the notice from campus officials.

The allegations were submitted to campus authorities on April 22, the letter said. 

A second fraternity, Sigma Chi, has also been placed on an “interim loss of recognition,” according to a separate letter obtained by Fox News Digital. 

The letter states the chapter is accused of hosting two events this month in which UA students “were provided with and consumed alcohol, and were knowingly and unknowingly given drugs,” allegations that directly violate the Arizona Board of Regents Student Code of Conduct.  

Campus officials allege that between the fall 2025 and spring 2026 semesters, Phi Delta Theta’s new members were “subjected to forced alcohol consumption, degradation, humiliation, hazing, and other threatening and endangering behaviors,” according to the notice.

Sigma Alpha Mu and Sigma Chi are scheduled to meet with the dean’s office this week to learn if the chapter’s loss of recognition is permanent, while Phi Delta Theta was set to meet with campus officials on April 15. 

“I mean that’s what you really think of when you think of fraternities, not so much sororities in my opinion, but not a surprising thing to know they’re still doing all that despite it being banned most everywhere I want to say,” UA freshman Acacia Fernandez told 13News.

“I do feel bad for the students who were affected by the hazing, just, you know, the social pressures that people have to go through to fit in, I feel bad for them honestly,” Fernandez reportedly said.

In a statement to Fox News Digital, a UA spokesperson confirmed the investigations being conducted into the three frats.

“The university takes these issues seriously, and they are currently being investigated by the Dean of Students Office,” the spokesperson said.

Fox News Digital reached out to Sigma Alpha Mu, Sigma Chi and Phi Delta’s local and national chapters for comment. 

Phi Delta Theta’s local chapter declined Fox News Digital’s request for comment.
