A man on the University of Minnesota Duluth campus, who reportedly had made suicidal threats and said he had a gun, was taken into custody Tuesday night by authorities.

Campus police learned of the man shortly after 9 p.m. from an acquaintance who called 911. Officials activated an alert system to notify the university community about the incident, and other local law enforcement agencies joined in the search for the man.

Officers found him about a half-hour later outside the school’s planetarium and took him into custody without incident. He was not carrying a gun, and no gun was found in the area.

The man, who apparently has no connection to UMD, was taken to a hospital and then to the St. Louis County jail, where he was booked on unspecified charges.

The university is currently on semester break.
