A 25-year-old man was arrested Sunday after pointing a gun at a downtown Portland food cart operator and firing a round into the air, police say.

Portland police said Dominique H. Mann threatened the food cart operator with a gun at Southwest Second Avenue and Oak Street, then left the area. Officers searched for him but weren’t successful.

Police said he later returned, however, and fired a round into the air.

Officers confronted Mann, but he was uncooperative and tried to walk away, police said.

An officer fired a foam-tipped round at him, police said. He then surrendered.

Authorities found a stolen, loaded semi-automatic handgun in his pocket, police said.

Mann, a Portland resident, is being held in the Multnomah County Detention Center on suspicion of theft, menacing and gun charges. His bail is $16,500, records show.

Police haven’t said which food cart was involved.
