Officials say Mantua Police Chief Shane Zilles was issued a citation Tuesday evening for driving under the influence of a controlled substance in his patrol vehicle. Mantua is near Brigham City in northern Utah.

According to the Utah Highway Patrol, a trooper stopped Zilles after they spotted the chief near Wellsville, where he was allegedly driving at a high rate of speed without lights or sirens activated and having difficulty staying in the appropriate travel lane.

“The chief cooperated with troopers in performing Standard Field Sobriety Tests. Troopers determined the chief to be in violation of the DUI-Drug statute and subsequently placed him under arrest,” Lt. Lee Perry stated Wednesday.

Zilles also agreed to a blood draw, but he reportedly told the trooper he was experiencing medical issues, so he was taken to a local hospital for medical clearance.

Perry said Zilles was cited and released to a family member at the hospital, which is common practice when individuals placed under arrest require medical testing and observation.

Zilles, a former Cache County sheriff’s deputy, has been chief of police in Mantua since the 2016 retirement of former Chief Mike Johnson.

Police in the small town beside the mountainous stretch of U.S. Highway 89/91 between Wellsville and Brigham City have long been criticized for what some see as excessive "speed trap" traffic law enforcement. In 2016, Sen. Lyle Hillyard, R-Logan, proposed a bill that would have capped revenue a municipality could collect from traffic fines. Hillyard specifically mentioned Mantua when speaking about the bill. The bill was defeated in the House Transportation Committee, which was of the opinion that it was an unwelcome state interference in local law enforcement.

In 2015, Zilles was awarded the Cache County Sheriff's Office Deputy of the Year award for his off-duty visits to local historian Ted Kindred.
