The University of Toledo student union building in Toledo, Ohio, was evacuated Saturday after reports of a suspicious person holding a gun in the air were reported there. A man has an "assault rifle" inside, one student wrote on Twitter.

Toledo police are on the scene assisting university police, and the school has sent out an alert to students to stay away from the building, as a "dangerous situation" is unfolding there. Students were reportedly "rushed out" of the building. It is unclear whether the purported gunman is a student at the university.

Early in the evening, the Toledo Blade reported that authorities had entered a nearby building and a SWAT team entered the student union at 6:45 p.m.

About 18,000 undergraduates and 5,000 postgraduates study at the university. This time of year is typically when American colleges hold their final examinations before summer break. This story will be updated as information rolls in.
