Louisville police are warning residents to be alert for a suspected impersonator posing as a police officer and attempting to stop drivers on area highways.

Louisville Metro Police investigators say the impersonator drives a black Chevy Tahoe that has red and white interior lights, along with lights and sirens.

He may wear clothes and equipment that make him look like an officer. Investigators also said he may identify himself as an officer or someone on a human trafficking task force.

Anyone who has encountered this individual is asked to call Louisville police at 574-LMPD.
