IOWA CITY, Iowa – One person has been arrested and a University of Iowa fraternity chapter has been suspended as authorities investigate a potential hazing incident, university leaders said Friday. KCRG-TV reports, according to a statement from the university, the arrest and suspension came after first responders were called to the Alpha Delta Phi fraternity house early Friday morning for a fire alarm, and they found several dozen pledges blindfolded in the basement.

One person was arrested and charged with interference with official acts. That person was NOT a student, and does not live at the house where the incident took place. Their name has not been released at this time. University leaders did not say how they were involved in the incident.

The University of Iowa’s Office of Student Accountability has suspended the operations of Alpha Delta Phi, pending the outcome of the investigation. The fraternity’s national chapter has also suspended the charter until further notice. The university released a statement saying it is committed to protecting the health and safety of its students and will address any behavior that puts student safety at risk.

The university has also reached out to the students involved in the incident to offer counseling resources. The investigation into the incident remains ongoing.
