Park City police arrested former professional snowboarder Nate Bozung early Saturday on suspicion of holding up a knife to one person and threatening to shoot another person with a rifle.

Bozung, 36, posted bail and was released from the Summit County jail Monday. He had been booked on suspicion of aggravated assault, unlawful possession of a firearm and marijuana possession. He has not been formally charged.

According to a probable cause booking statement filed by Park City police, Bozung was among a group who had been at a bar late Friday or early Saturday. The group returned to Bozung’s apartment in the 400 block of Ontario Avenue.

Bozung was intoxicated and agitated, witnesses told police, though the statement doesn’t specify why he was agitated. The booking statement says Bozung retrieved two kitchen knives and placed one of them against the throat of one person. That person did not suffer an injury.

Bozung “damaged a large bay” window, the statement said, and most or all of the rest of the group left the apartment. A neighbor then followed Bozung as he went to his 2013 Jeep Wrangler and retrieved ammunition, the statement says.

Then Bozung went back to the apartment and picked up a 5.56 rifle, often referred to as a AR-15-style rifle, the statement says. The neighbor told police Bozung said, “I’m going to kill you!”

Police were called, set up a perimeter and obtained a search warrant. Bozung did not answer an officer’s calls to his cellphone, but later spoke to a family member and surrendered, the statement says.

Bozung later told police he blacked out for part of the night, the police document says.

Court records also show Bozung had a separate arrest warrant pending when he was booked into jail Saturday. That warrant stemmed from a misdemeanor charge against him in a Heber City justice court of intoxication and an infraction charge of disorderly conduct. A court docket says Bozung failed to appear for a scheduling hearing March 22. A judge then issued a warrant for Bozung’s arrest.
