Popping balloons reportedly triggered an active shooter warning on University of Michigan’s Ann Arbor campus Saturday.
The initial warning from the Division of Public Safety and Security read simply, “UM EAlert Ann Arbor: Active shooter in Mason Hall . Run, hide, fight.” (RELATED: Five Dead In Active Shooter Incident In Illinois)

Students responded to the alert by barricading themselves in wherever they happened to be at the time and tweeting to those outside the school asking for updates about the possible shooter’s location.

There does not appear to be an active threat at UofM at this time. Reports of shots fired on campus are unfounded at this time. UofM DPSS continues to investigate and asks that you stay clear of the area.

Shortly thereafter, several outlets reported the “all-clear,” saying that unconfirmed reports of popping balloons may have been what caused the alarm.
