Rapper Marion “Suge” Knight was arrested Wednesday on charges of assault and domestic violence, after allegedly beating his girlfriend while wielding a knife, police said.

Knight, 43, was also charged with two drug offenses, as he was found to be in possession of ecstasy and the prescription narcotic Hydrocodone.

According to the Las Vegas Metropolitan Police, officers received a call about a car that was out of control on the Strip, at about 6:30 p.m.

Police said that Knight’s girlfriend of three years told officers that the rap mogul hit her in the head during an argument, while he was driving. She made an attempt to escape, grabbing the steering wheel and causing the vehicle to hit a curb and stop abruptly. She then got out of the car and ran away, with Knight pursuing her.

Luckily for her, police officers arrived at the scene just as Knight was standing over the woman, threatening her with a knife. He was arrested on charges of assault with a deadly weapon, possession of a controlled substance, possession of dangerous drugs without a prescription, and battery domestic violence. His girlfriend was taken to Spring Valley Hospital, where she was treated for minor injuries.

Over the years, Knight has had many problems with the law. In 1996, he was sentenced to prison for violating his probation on a previous assault case by beating a member of the rival gang Crips at the MGM Grand Hotel. The incident was caught on a surveillance camera and took place a few hours before the Death Row Records founder and rapper Tupac Shakur were attacked in a drive-by shooting. Knight was driving the vehicle in which Shakur was fatally shot and was also slightly wounded himself.

Knight was also named by police as a suspect in the assassination of rap artist Christopher Wallace, who was known as Notorious B.I.G. and had signed to a rival record label. But Knight was never charged and the murder remained unsolved, like the one of Shakur.

Knight got out of prison in April 2001 and the following year his record label was closed, following an investigation that stemmed from allegations of murder, drug trafficking, money laundering and gun running. The company pleaded guilty to misdemeanor tax charges.

Following Wednesday’s arrest, Knight posted a $19,000 bail and was scheduled to be released later during the day, with a promise to appear Sept. 26 in Las Vegas Justice Court, a court spokeswoman said. His lawyers declined to comment on the matter.
