Katt Williams has been arrested in Portland, Ore.

The comedian was on his way to Nick Cannon's Wild 'N Out Live concert on Friday when he allegedly attacked the driver who was taking him to the event over whether or not he would also take Williams' pet dog.

According to TMZ, the the driver was left with cuts and bruises on the face and was taken to the hospital. 

Katt left the scene before police arrived, but they spoke with him Saturday morning. Williams, who's been locked up since, has been charged with assault in the fourth degree and will be arraigned today. He's also facing a warrant out of Georgia.

Just last week, the comedian threatened to beat up Kanye West after the Chicago rhymer blasted Nick Cannon for talking about Kim Kardashian's body.

Williams also said he's going to hurt Kevin Hart because Hart talked about Katt's drug use and how it affected his career. At the time, the Night School actor was defending Tiffany Haddish after Williams criticized her stand-up comedy skills.

Do you think Williams will ever be able to stay out of trouble?
