Increasingly erratic alleged comedian Katt Williams hit up a Target in Sacramento last weekend ... and hit an employee in the face for what looks like no reason at all.
There's no audio, so we don't know what was said, but Katt Williams' slap appears to come out of nowhere; the Target guy's doesn't look like he's looking to start $h!t ...
Williams was on the run from the cops at the time the slap went down. He gets in trouble with the law a fair amount, so often it's hard to keep the arrests straight.
After the slap, the employee pulls out his phone and calls police, who eventually arrested Katt, who attempted to make his getaway in an electric cart ... seriously.
