The University of Michigan Division of Public Safety and Security gave the all-clear at about 8 p.m. Saturday after authorities investigated reports of an active shooter on campus.
Earlier in the day, the University of Michigan sent out a run-hide-fight alert due to reports of an active shooter through its emergency alert system. Multiple buildings were locked down and some students barricaded themselves in rooms.
It happened at Mason Hall, an academic building off State Street by the Diag.
Police blocked off the area for hours after hearing reports of an active shooter on campus.
