SIOUX CITY, Iowa (AP) – Authorities say they’re investigating a man who has been posing as a police officer and making traffic stops in western Iowa. The Woodbury County Sheriff’s Office says two traffic stops were conducted late Saturday night and early Sunday morning near Correctionville and Anthon, Iowa. KTIV-TV reports no threats were made during the fake traffic stops.

According to a news release, the vehicles were pulled over by a seemingly new Dodge Charger with red and blue lights in the dash. The release says the man driving the Dodge identified himself as a member of law enforcement. Those who were pulled over later reported the incidents to police.

The sheriff’s office says officials making traffic stops will be dressed in complete uniform and can display their credentials upon request.
