Fairfax City?  Yeah, it's a real thing.  Most people think about Fairfax County, but there's a little area near the Fairfax County General District Court that comprises Fairfax City.

And they have a police force.

And they arrest people.

According to this REPORT, a man has been charged with DUI and assaulting a police officer in Fairfax City.  Allegedly, the assault occurred during the suspect's processing.

Fun fact:  body worn cameras aren't always turned on in Virginia during booking.  Jail camera feeds can be discovered, however.
