Suge Knight is taking Chris Brown and the owners of a US nightclub to court over a 2014 nightclub shooting.
The former rap music mogul was shot seven times at a party hosted by the R&B singer.
The case, filed at LA Superior Court, accuses Chris Brown and West Hollywood club 1 Oak of failing to have adequate security and allowing at least one armed person into the venue.
Suge Knight suffered gunshot wounds to the abdomen, chest and left forearm.
Suge Knight is currently on trial for murder over a fatal hit-and-run case.
But it’s claimed what happened in the club left the rapper with long-term problems that explain his actions.
He was charged with running over two men with his pickup truck outside a burger stand in Compton, killing one and seriously injuring the other.
His lawyers have said he was trying to get away from armed attackers in the collision, which happened last January.
They also say he was still recovering from the first incident and scared for his life.
“Mr Knight was still extremely frail from his gunshot injuries less than five months earlier,” his lawyer, J. Tooson, wrote in a statement.
The new lawsuit doesn’t say how much money Suge Knight is after but he wants Chris Brown and the nightclub to pay past and future medical expenses for his injuries.
Suge Knight’s lawyers say 1 Oak should have taken special security precautions because they claim events hosted by Chris Brown have a history of violence.
It accuses the R&B star of gang ties and a “well-documented track record of hosting events and/or parties in which violence frequently erupted”.
Chris Brown hasn’t been implicated in the shooting and no arrests have been made.
“As a result of the negligence of the defendants, one or more unknown individuals were allowed access to the event with weapons, including firearms,” the lawsuit says.
“As a foreseeable result, gunshots were fired by those admitted into the event and (Knight) was shot and seriously injured.”
So far, there’s been no response from Chris Brown.
Suge Knight was also shot and wounded at a party hosted by Kanye West in Miami Beach in 2005.
He sued the rapper, blaming him for poor security but a judge ruled in Kanye West’s favour after concluding there was no evidence a shooting was foreseeable.
Suge Knight was a key player in the gangster rap scene in the 1990s.
He’s been held under tight security since he turned himself in to authorities after the fatal collision.
His Death Row Records label once listed Dr Dre, Tupac Shakur and Snoop Dogg among its artists.
He lost control of the company after it was forced into bankruptcy.
Suge Knight was sentenced to five years probation for assaulting two rappers in 1992.
He was then jailed in 1997 for violating his probation – by taking part in a fight at a Las Vegas hotel hours before Tupac Shakur was fatally wounded in a drive-by attack as he rode in Suge Knight’s car.
