Reports TMZ:

Katt wasn’t done after leading cops on a crazy three-wheeled chase through Sacramento on Sunday — because moments later, he hit up a Target … where he belted an employee IN THE FACE … and TMZ has footage of the face-to-hand contact.

There’s no audio, so we can’t tell what the argument is about — but by the looks of the employee’s body language before the wallop (placing his hand on his chest) the guy wasn’t looking for a fight.

Then out of nowhere Katt winds up and slaps him in the face — at which point the employee pulls out his phone and, according to an eye witness, he calls police.

Video of the aftermath surfaced on the Internet this week, showing Katt making his getaway in an electric cart … before police arrive. We hate to say it, but it’s hilarious.

According to sources at the store, Katt then ditched the electric cart and got back on his three-wheeled motorcycle. He was not arrested.

We spoke to a rep for the Yolo County DA’s office, who tells TMZ, the case is currently under review … and charges have not yet been filed against the comedian.
