The chief of the northern Utah police department that serves North Logan and Hyde Park resigned Thursday, weeks after he was charged with driving under the influence in Idaho.

Ulysses Michael Black was arrested on June 18 in Fremont County, Idaho, court records indicate. He pleaded not guilty to the DUI charge on June 21 and posted $2,000 bail.

Black tendered his resignation to Hyde Park Mayor Bryan Cox and North Logan Mayor Lyndsay Peterson on July 7. In a joint letter, both mayors wrote that the North Park Police Department chief resigned “for personal reasons and plans to transition into retirement.”

The Cache Valley Daily reported that Assistant Chief Justin Olsen will take over as interim chief for North Park police while the North Park Police Commission searches for Black’s replacement.

Black had been leading the North Park Police Department since January 2020. His resignation caps off 27 years in law enforcement. Black served as a Willard County police officer, then a deputy for the Box Elder County Sheriff’s Office before joining the North Park Police Department in 2001.

According to the North Park police website, which still identified Black as police chief as of Monday afternoon, Black considered being police chief an “honor.”

“As Chief of Police my expectations are to have a safe, positive, responsive, competent and ethical staff that will put our communities needs first,” a statement on the website from Black reads.

Black is scheduled to appear before the Fremont County Magistrate Court in St. Anthony, Idaho, on Aug. 3.
