Tucson police are investigating incidents involving men posing as cops who made traffic stops.

The stops were made between June 10 and June 20, said Sgt. Maria Hawke, a Tucson Police Department spokeswoman.

The imposters used a dark-colored Ford Crown Victoria, which has been recovered by police.

No information was released to what led to the recovery of the vehicle.

The sedan had low-profile red and blue lights above the dashboard, and additional lighting in the vehicle’s rear window area, Hawke said.

The vehicle did not have police markings on it, or rooftop emergency lights.

Detectives want to talk to anyone who was stopped by the imposters. These men were not dressed in a police uniform, and might have identified themselves as a law enforcement or government agent, said Hawke.

No citations were issued by these men, Hawke said.

Detectives are asking that anyone who was stopped under these circumstances to call 911 or 88-CRIME.

Motorists who doubt the identity of any law enforcement officer can call 911 to verify the officer’s identity, Hawke said.
