A 20-year-old Austin man who allegedly chased two people while he had a gun has pleaded not guilty.

Tywan Clark pleaded not guilty Thursday in Mower County Court to gross misdemeanor charges for possession of a pistol without a permit and possession of a pistol while using a controlled substance.

Police arrested Clark after homeowners in the area reported a foot chase in the 2000 block of Sixth Ave. NE around 6:30 p.m. on Sunday. A bystander allegedly saw Clark walking back and forth on the road and toss his gun in the back of a truck near the 2100 block. An officer arrested Clark after finding a loaded 9mm semi-automatic pistol in the back of a truck. Though the magazine was empty, there was one live round in the chamber, the report says. According to the court complaint, Clark also admitted that he tossed a bag of marijuana in a yard; however, police could not find the bag.

His pretrial is Sept. 21.
