Police impounded the 52-year-old Dupont man's Nissan Frontier pickup truck that was equipped with red-and-blue flashing police lights, sirens, K-9 stickers, a public address system and a police scanner.

Also found inside the truck were two police-type badges, handcuffs and a handgun, police said.

After serving a search warrant at the man's home, Lakewood investigators said they found several badges, a black windbreaker and T-shirts with police markings and a small arsenal of weapons including a rifle fitted with a high-powered sniper scope.

Lakewood police said they are looking for possible victims of the man who may have been passing himself off as a police officer for several months.

"We have reason to believe that he has told others, including law enforcement, that he was affiliated with another law enforcement agency," said Lakewood Police Lt. Heidi Hoffman.

Lakewood police said they began investigating the man a month ago after a patrol officer was told by employees at Champions Sports Bar that the man came in to check on someone parked in a handicapped spot, claiming he was a Pierce County sheriff's deputy.

"We're very concerned that he may have been conducting traffic stops, and so if there's anyone out there who's been stopped by this man or approached and had him identify himself as law enforcement, we need to talk to those witnesses," said Hoffman.

Anyone with information in the case or may have been contacted by the man is asked to call Lakewood police at 253-380-5011.
