Police in Montgomery County are searching for a man they say posed as a police officer, pulled over a driver and stole her purse and cell phone.

The victim, a 39-year-old woman, told police she was driving down Avenel Road in Silver Spring around 11:45 a.m. Wednesday when the driver of the car behind her began honking his horn and motioning for her to pull over.

When the victim didn’t stop, the other driver pulled up next to her, yelled that he was a police officer, and motioned to a badge pinned to his vest. This time, the woman pulled over, police said.

The man asked for the woman’s license and registration, and instructed her to get out of the car and sit on the curb while he searched the vehicle.

The man took her purse and cell phone from the car, got back into his car and drove away. The victim, who was not injured, then called police.

Police described the suspect as a black man, about 26 years old, about 5’10” tall, and weighing about 190 pounds. He had short, curly hair, and tattoos on both arms. He was wearing a black baseball hat with a police badge emblem, a black vest similar to a police vest with a silver badge attached, black cargo pants and black boots.

Despite his accessories, police do not believe he is an officer or affiliated with a police department.

The suspect was driving a small, black, compact car with blue Maryland tags and no police lights or sirens. He was last seen driving toward New Hampshire Avenue.

Anyone with information about the incident or the suspect can call police at 301-565-5835.
