The cops went back to deal with the unruly driver, but as they made their way to his car, the man quickly pulled into an open parking space.
He was now legally parked. But they decided to talk to him anyway.
That's when a nearby DPT employee intervened, telling the cops that the driver was the same man who had vandalized her vehicle after she wrote him a ticket for double-parking.
The DPT employee told police that after writing his ticket, she pulled forward in her vehicle, stopped, and got out to cite another parked car. That's when the man came up to her three-wheeler and stuck a knife into the rear tire, according to police reports.
Police searched the man and found a knife in his pocket. The man was arrested on suspicion of puncturing the DPT tire, then cited for vandalism of city property.
And he still is on the hook for that parking ticket.
