IOWA CITY — The University of Iowa this semester has investigated, or is continuing to investigate, more allegations of hazing at two of its fraternities — one of which nearly faced additional reprimand for hosting a gathering “at which llamas were present.” The UI Sigma Pi chapter — which in recent years faced reprimand for alcohol and arrest violations — on Feb. 1 was notified of the UI Office of Student Accountability’s investigation into allegations it hazed a new member on or around Jan. 31. According to a UI letter to Sigma Pi — which The Gazette obtained through a public records request but came heavily redacted — investigators suspected the chapter “directed, encouraged, or approved” of a new member engaging in “dangerous physical activity.”
