Katt Williams Arrested Again

Katt Williams was arrested again last night ... this time in Dunnigan, CA (about 40 miles from Sacramento) on an outstanding warrant.

Yolo County Sheriffs deputies popped Williams at a gas station following a traffic stop, this according to KCRA. An arrest warrant for Williams had been issued on Thursday out of Sacramento County for a reckless driving incident last month.

Williams missed his gig in Houston on Friday night and the venue for his show in New Orleans on Saturday night has announced his performance there is canceled as well.

This is just the latest in an ongoing string of legal troubles for Williams -- including a bar fight in which he allegedly threw a rock at a car, a lawsuit over a bizarre onstage meltdown, and of course ... slapping a Target employee in the face.
