BALTIMORE (AP) — Baltimore police are looking for men they say are posing as officers and robbing motorists.

The police department says the four men have been seen wearing black tactical vests with the word “AGENT” on them and driving a gray Dodge Caliber.

Police say the suspects pulled over a car on Friday, searched the car and took the motorist’s money.

On Saturday, police say the suspects pulled up behind a motorist whose tire had blown out. Police say the suspects then robbed the driver.

Police say the suspects are black males. They say they don’t know whether they are armed.

They’re asking anyone with information about the suspects to contact authorities.
