In Ohio, traffic stops must be made by a marked law enforcement vehicle, Middletown Police Maj. Scott Reeve told the Journal-News.
“Every so often, a detective will make a stop in an unmarked car, but that is usually when they see some type of suspicious activity,” Reeve said.
If someone suspects they are being pulled over by a person who is not a police officer, they should drive to a populated area before stopping and call 911, Reeve said.
The vehicle in the alleged Middletown incidents was last seen at Bull’s Run Arboretum on Rosedale Road traveling south on Breiel Boulevard, according to police.
The Middletown Division of Police posted a warning Sunday afternoon on Facebook about the reported false stops.
If you know who these people are or have seen the vehicle, call dispatch at 513-425-7700.
