One non-student was arrested for underage drinking during the Sunday morning disturbance. No injuries were reported.
University spokeswoman Teri Rizvi tells WHIO-TV that campus police first turned out in response to a false fire alarm. Within the hour, riot-equipped officers from departments in the Dayton area were dispatched to help quiet the disturbance.
The station says students were climbing on cars, throwing bottles, yelling at police and left the street littered with trash and beer cans.
Elsewhere, the streets were jammed for the annual St. Patrick's Day Parade in Cleveland Sunday afternoon. The parade included nearly 150 marching units with Siberian huskies and shire horses joining traditional Irish troupers.
