Suge Knight, mug shot above, was arrested yesterday by Las Vegas cops for assault with a deadly weapon, possession of controlled substances which were vicodin and ectasy, and domestic violence.

Police say Suge punched his girlfriend of three years, Melissa Isaac, in the back of the head in the car. We’re not sure if that happened before or after she says she grabbed the steering wheel to deliberately cause an accident. After the car stopped the girlfriend ran, Suge caught her, and police say they saw him kick her in the head, and had a knife in his hand.

After being released from jail last evening, Suge partied at Drai’s until the wee hours of the morning. He is due back in court September 26.
