Officials in northeast Kansas are warning people to be on the lookout for a man who is impersonating a police officer who stops vehicles and demands to be allowed to search them.

Five incidents have been reported this week.

KCLY reports the first report came in Sunday evening. On Wednesday night, the man stopped a vehicle near Liberty, Nebraska, just north of Marysville.

The man, who wears a black uniform with a badge, uses a single red light on his white 4-door truck. He is described as white, in his 40s, about 6-foot-1, with brown hair and a black mustache.

Marysville Police Chief Todd Ackerman says several area agencies and the Kansas Highway Patrol are searching for the suspect’s vehicle.
