UPDATED at 1 p.m. with additional information.

Police in Columbia, Mo., and at the University of Missouri-Columbia found a woman who was described as possibly suicidal after she was seen near the flagship campus carrying a handgun Wednesday.

An alert said the situation was "all clear" and the woman was unharmed.

An initial alert around 11:30 a.m. said there was an "active threat" near the intersection of Hitt and Locust streets, which is just outside of the campus.

Just before 1 p.m., scanner traffic indicated that police found the woman off campus without incident. The university confirmed that shortly after.

Multiple campus alerts went out over the course of an hour and a half, telling the Mizzou community to stay in place.

Several alerts said she was walking through part of campus.

On social media, students said they were corralled into the basement of one campus building as a precaution. Mizzou's university account encouraged students to contact their parents and tell them they're safe.
