Bozeman, MT -

Montana State University police are searching buildings and telling people to stay inside after receiving a report of two men carrying a rifle on campus.

An alert sent out by the university Wednesday morning says police received a report the men were crossing 11th Avenue in Bozeman and heading toward the center of the Centennial Mall.

The Bozeman Daily Chronicle reports one man is wearing a hunter's orange hoodie and the other a green or gray jacket and a baseball hat.

Officers are advising people on campus to stay inside and lock their doors.

Bozeman police say nearby schools have been locked down. Police officials say the measure is a precaution and they have no reason to believe a gunman is heading toward the schools.
