Video appears to show Sean 'Diddy' Combs beating singer Cassie in hotel hallway in 2016
"The gut-wrenching video has only further confirmed the disturbing and predatory behaviour of Mr Combs," said Douglas Wigdor, a lawyer for Cassie who has filed other lawsuits against Combs.
"Words cannot express the courage and fortitude that Ms Ventura has shown in coming forward to bring this to light."
According to the lawsuit, Combs earlier in the evening became "extremely intoxicated" and punched Ventura, giving her a black eye.
After he fell asleep she tried to leave, the suit says. This is apparently where the video begins. Ventura can be seen heading to a bank of elevators with a packed bag.
Then Combs awoke and began screaming at her, following her down the hall, the suit said.
He violently grabs her and yanks her to the ground, kicks her, and throws vases in her direction in the video.
The lawsuit says she managed to get away, but later returned out of fear that she would face greater abuse if she didn't. As she returned, hotel staff urged her to go back to her apartment, the suit says. She would flee and hide out with a friend in Florida.
The lawsuit alleges Combs paid the hotel $US50,000 for the security video.
Criminal charge over video unlikely
It is unlikely Combs could be criminally charged in the attack. The statutes of limitations for assault or battery in California run from one to three years depending on whether they're charged as misdemeanours or felonies.
The video's release comes as Combs and his legal team had begun to push back against the allegations that had come in a steady stream since November.
They recently filed motions to dismiss parts of a lawsuit alleging he sexually assaulted a woman in 1991, and to dismiss all of a lawsuit alleging he and two other men raped a 17-year-old girl in 2003. The court filings called both sets of allegations false.
On March 25, Homeland Security Investigations served search warrants on Combs's homes in Los Angeles and Miami in a sex-trafficking investigation. His lawyer called it "a gross use of military-level force."
The investigation is continuing. Combs has not been charged.
Combs, a three-time Grammy winner and the founder of Bad Boy Records, is among the most influential hip-hop producers and executives of the past three decades. He turned his hip-hop success into a broader business empire that includes private-label spirits, fashion, and a TV network.
He has had to step aside from some of his business roles since the allegations
