CHANTILLY, VA (WUSA9) -- A man who arrested a driver—whom he got in a crash with—is facing charges for impersonating a police officer. He told officers he took a criminal justice course, so he had the authority to arrest people.

Fairfax County Police said a real officer arrived on the scene of a crash at 5:45 p.m. Wednesday at Lee Jackson Memorial Highway and Elmwood Street in Chantilly.

The officer immediately noticed one of the drivers was in handcuffs and appeared to be under arrest. Arta Javanbakhtamarlouei told police he felt threatened by the way the driver was acting, so he put the handcuffs on the driver.

But Javanbakhtamarlouei had more than handcuffs on him.

Fairfax County Police offered the following tips to help people verify a police officer:

  • Ask for the officer’s credentials, to verify they are who they stated they were.
  • Officers should always introduce themselves and advise who they work for.
  • Observe their uniform patches and verify it is the agency they told you.
  • Be familiar with the police cruiser markings in your jurisdiction to assist you in identifying their authenticity.
  • If you ever feel uncomfortable, don’t hesitate to call 9-1-1 to verify the identity of officer you are dealing with. Dispatchers will be able to confirm this information over the phone and use GPS coordinates to verify an actual officer’s status.
