The University of Arizona has suspended recognition of the fraternity Phi Gamma Delta for reported violations of the student code of conduct, the university said Wednesday.

The school alleges the fraternity, known as FIJI, committed multiple rules violations including hosting unregistered events where alcohol was given to minors and that is has engaged in hazing of new members.

The university told the fraternity that it must cease all activities on campus pending the outcome of the school's investigation.

The school said a complaint alleging the violations of the student code of conduct was forwarded to the Dean of Students Office by campus police during its investigation into the death in April of a student who fell from a cooling tower on the roof of a campus dorm. The student was a member of Phi Gamma Delta and had attended a function at the fraternity house the night he died.

In its complaint, the university said the fraternity, which was already on probation, hosted unregistered events where alcohol was served to minors on multiple occasions including one in December, six in January, seven in February, four in March and two in April.

The hazing includes allegations of physical assaults of new members, making them clean up the fraternity house, throwing food at them, not letting them eat at the fraternity house, making them perform acts of servitude and forcing them to exercise, the university stated in a letter to the fraternity.

In its report, campus police said there was evidence of marijuana use at the fraternity house and that the chapter president instructed members to deny to police that alcohol was being consumed at the house and to hide activities from the school and the fraternity's national organization.

The university said all of the events occurred when the fraternity was on probation and had been suspended from having events with alcohol.

The "interim suspension of recognition has been imposed pending the outcome of this investigation because it has been determined that your organization presents a substantial risk to members of the university community," the school said in its letter.
