WHEATON, MD (WUSA9) - It's bad to impersonate a police officer.
It's worse when you try to pull over a real police officer.
Police say John Angelini, 51, of Baltimore tried to pull over an off-duty officer while he was impersonating an officer.
Angelini was driving a Crown Victoria on the ICC on Wednesday when police say he pulled up to an off-duty officer and turned on a siren.
The off-duty officer then turned on his real siren, and pulled him over.
Police say the car looked like a real cop car, complete with lights, radio, stop sticks and flex cuffs.
Angelini faces one count of impersonating an officer.
