Vincent Angelini (Montgomery County police)

A Baltimore man impersonating a police officer was arrested Wednesday after trying to pull over an actual police officer, authorities said.

At about 8:15 p.m., a Montgomery County detective was traveling eastbound in an unmarked vehicle on the Intercounty Connector near Georgia Avenue when he saw a Ford Crown Victoria that appeared to be an unmarked police vehicle traveling alongside him, Montgomery police said in a statement.

Vincent Angelini, 51, the driver of the Crown Victoria, positioned his vehicle behind the detective’s vehicle and activated a siren, the statement said, and the detective believed Angelini was attempting to pull him over.

However, after activating the siren, Angelini abruptly changed lanes and accelerated past the detective, according to the statement, leading the detective to pull Angelini over.

The detective noted red and blue grill lights and antennae on the exterior of Angelini’s car, while the car’s interior was made up to look like a police car, with a radio microphone, emergency lights and switches, a camera affixed to the windshield, a siren and flex cuffs, police said.

The detective determined that Angelini was not a police officer and placed him under arrest, police said. Angelini was charged with one count of impersonating a police officer and released on a $2,500 bond.

Police asked anyone who saw Angelini pass himself off as a police officer to call them at 240-773-6370.
