A written bomb threat caused University of Montana Western officials to call for a campus evacuation Friday morning in Dillon.

Dillon Police Chief Don Guiberson said a university staff member discovered the threat on a piece of paper in the school’s Bulldog Athletic and Recreation Center.

Police were notified around 9:15 a.m., and the school was evacuated shortly thereafter, Guiberson said.

Law enforcement cleared the campus around 12:45 p.m., and the campus reopened at 1 p.m., according to a news release from the chancellor’s office.

Class will resume at 8:15 a.m. Monday, but 125th Founders Anniversary events will be rescheduled at a later date.

Meanwhile, Guiberson said the BARC athletic center will remain closed until 8 a.m. Saturday.

Multiple government, rescue, and law-enforcement agencies responded, including Dillon police; Beaverhead County Sheriff’s department; local and volunteer firefighters; Montana Fish, Wildlife and Parks; and the Bureau of Alcohol, Tobacco, Firearms and Explosives, among others.

“I was impressed by the quick evacuation by our staff, students and faculty. I am thankful to our amazing law enforcement agencies who were swift to act and diligent in ensuring the safety of our community,” said Chancellor Weatherby in the news release.

Guiberson said law enforcement has not yet identified a suspect and the investigation into the matter remains ongoing.
