DULUTH (AP) — The man arrested at Duluth East High School last week has been charged with threatening violence and possessing a machine gun conversion kit.

35-year-old Travis Busch was at the school working as a job coach in the cafeteria when police say they received a tip that he made a series of threats related to exchanging gunfire with law enforcement.

In court Tuesday, Busch's public defender argued the comments were made to a close relative and not to anyone at the school.

Officers confiscated a pistol from Busch's vehicle and four guns, ammunition and accessories from his home.

Judge Dale Harris set bail at $200,000.
