[Ohio University Athens]Harry How/Getty Images * Ohio University suspended all 15 fraternities on its campus after seven allegations of hazing at different fraternities were submitted within the first three days of October. * The week prior to the submissions was National Hazing Prevention Week, and the Sorority & Fraternity Life Office at OU held events for all of the sororities and fraternities on campus where the process of identifying and reporting hazing was explained. * Two of the seven fraternities were identified as ACACIA and Alpha Epsilon Pi, both of which were issued cease-and-desist letters. The letters did not elaborate on the content on the complaints, aside from noting that the "health and safety" of multiple students was put at risk. * The eight fraternities that were not reported will be presented with steps to be taken off suspension once the other five are identified, although what those steps will consist of is not yet clear. * No fraternities will be allowed to participate in OU's Homecoming celebrations next week, nor can any fraternities hold meetings, host activities, or communicate as a group for the time being. * Visit Insider's homepage for more stories.
