Hip hop entrepreneur Marion “Suge” Knight posted $19,000 bail Wednesday after being arrested on assault and drug charges in a Las Vegas parking lot – he was allegedly found by police violently beating his girlfriend of three years.

Marion Knight, founder of the now bankrupt Death Row Records, was arrested and taken into custody Wednesday morning when Las Vegas police was called to a parking lot where the entrepreneur was reportedly hitting a woman and holding a knife.

“A citizen sees the beating in a parking lot, police get there fast, they see him beating her. It’s a good solid case,” Las Vegas police Lt. Chris Carroll said, as quoted by the Associated Press.

Carroll said Knight, whom he estimated to be twice the size of the woman, was “on top of her, actually in the act of violently beating her when the officers arrived, with the knife in his hand.”

Police spokesman Jacinto Rivera said at least one of the officers drew a Taser gun as they approached the ongoing scuffle. Knight however dropped the folding knife he had been holding and was taken into custody without incident.

The woman, whose identity has not been revealed by the police but who said she was Knight’s girlfriend of three years, was taken to hospital. She received medical treatment for non-life-threatening injuries, Carroll said. She had not been stabbed.

Knight was booked on charges of assault with a deadly weapon, possession of a controlled substance and possession of dangerous drugs without a prescription (Knight had Ecstasy and hydrocodone on him upon being arrested), reports the Associated Press.

The 43-year-old Knight posted $19,000 bail. He is scheduled to appear in Las Vegas Justice Court on Sept. 26.

Knight and his girlfriend ended up in the parking lot after they reportedly quarreled in their car, according to Rivera. Knight was driving, they got into an argument, he allegedly punched his girlfriend in the head and she grabbed the steering wheel so as to stop the car, after which she jumped out of the vehicle.
