Sean Combs - also known as P Diddy and Puff Daddy - says he is "disgusted" by his behaviour in a recently released video from 2016 which shows him attacking singer Cassie.
The video is the latest development after a series of serious allegations in recent months.
But what exactly is he accused of - and what has he had to say about it?
What are the allegations?
The most recent development is the CCTV footage, which appears to show Combs punching and kicking Cassie in a Los Angeles hotel hallway on 5 March 2016.
The video was obtained by CNN.
The R&B singer, whose real name is Cassandra Ventura, was his protege and girlfriend at the time.
The video also shows the rapper shoving and dragging her across the floor, and throwing a vase in her direction.
But it follows raids on the 54-year-old's homes in Los Angeles and Miami by Homeland Security Investigations agents on 25 March, as he faced a series of public allegations of physical and sexual violence.
Raids on the rapper's properties were part of an ongoing sex-trafficking investigation by federal authorities in New York.
According to Sky's US partner network NBC News, three women and a man were interviewed by federal officials in Manhattan in relation to the probe.
The investigation includes further allegations of sexual assault, solicitation, and distribution of illegal drugs and firearms.
Combs has also recently faced several lawsuits accusing him of sexual misconduct and other wrongdoing.
In February, a music producer alleged Combs coerced him to solicit prostitutes and pressured him to have sex with them.
Combs's lawyer responded by saying: "We have overwhelming, indisputable proof that his claims are complete lies."
Combs was named in April in a lawsuit that alleges his son sexually assaulted a woman working on a yacht chartered by his father.
His son is accused in the suit of spiking a woman's drink and groping her, while it is alleged Combs created the circ*mstances that led to the assault and paid to cover it up afterwards.
Cassie also sued him in November alleging she was trafficked, raped, plied with drugs and beaten by Combs over a 10-year period.
The lawsuit claimed he forced her to have sex with male prostitutes while he filmed them. The case was settled the day after it was filed.
The newly released CCTV footage of the hotel incident resembles some of the descriptions in that lawsuit.
Also in November, Combs was sued by Joie Dickerson-Neal who alleged he drugged and sexually assaulted her when she was a psychology student at Syracuse University in January 1991. She also accused him of filming the attack.
Combs rejected the claims as "made up and not credible", with a spokesperson branding them "purely a money grab and nothing more".
Another of the rapper's accusers is a woman who claims he "gang raped" her two decades ago after she was plied with drugs and alcohol at the age of 17.
What has Sean Combs said?
In a statement in December, Combs described the claims he was facing then as "sickening" and alleged his accusers were "looking for a quick payday".
"Let me be absolutely clear: I did not do any of the awful things being alleged. I will fight for my name, my family and for the truth," he said.
Following the raids on his house in late March, Combs's lawyer Aaron Dyer said there had been a "gross overuse of military-level force as search warrants were executed".
"There is no excuse for the excessive show of force and hostility exhibited by authorities or the way his children and employees were treated," he added.

Mr Dyer said Combs had not been arrested or had his ability to travel restricted, and neither had any of his family members.
"This unprecedented ambush - paired with an advanced, coordinated media presence - leads to a premature rush to judgement of Mr Combs and is nothing more than a witch hunt based on meritless accusations made in civil lawsuits.
"There has been no finding of criminal or civil liability with any of these allegations. Mr Combs is innocent and will continue to fight every single day to clear his name."
Mr Dyer, in a response to the allegations against Combs' son in April, called the lawsuit against him and his father "lewd and meritless" and said it was "filled with the same kind of manufactured lies and irrelevant facts we've come to expect" from the alleged victim's lawyer.

After the CCTV footage of the attack on Cassie came out in May, the rapper released a video message saying he was "truly sorry".
"It's so difficult to reflect on the darkest times in your life, but sometimes you got to do that," he said.
"I was f***** up - I mean I hit rock bottom - but l make no excuses. My behaviour on that video is inexcusable. I take full responsibility for my actions in that video. I was disgusted. I was disgusted then when I did it. I'm disgusted now.
"I went and I sought out professional help. I got into going to therapy, going to rehab. I had to ask God for his mercy and grace. I'm so sorry. But I'm committed to be a better man each and every day. I'm not asking for forgiveness. I'm truly sorry."
What have Cassie's lawyers said?
After the footage emerged, Douglas H Wigdor, lawyer for Ms Ventura, said in a statement: "The gut-wrenching video has only further confirmed the disturbing and predatory behaviour of Mr Combs.
"Words cannot express the courage and fortitude that Ms Ventura has shown in coming forward to bring this to light."
Meredith Firetog, who also represents Ms Ventura and other women who have sued Combs, said the apology was "more about himself than the many people he has hurt".
"When Cassie and multiple other women came forward, he denied everything and suggested that his victims were looking for a payday," the lawyer said in a statement.
"That he was only compelled to 'apologise' once his repeated denials were proven false shows his pathetic desperation, and no one will be swayed by his disingenuous words."

Have there been any repercussions?
Two properties owned by Combs were searched by federal agents on 25 March.
NBC News reported several phones were also seized from the musician in Miami before he was scheduled to depart on a trip to the Bahamas.
Last year, Combs stepped down as chairman of his cable television network Revolt amid the sexual abuse allegations.
Revolt announced Combs's decision via social media. It is not clear if he will ever return to the media company - which previously said he had "no operational or day-to-day role" at the network.
"This decision helps to ensure that Revolt remains steadfastly focused on our mission to create meaningful content for the culture and amplify the voices of all Black people throughout this country and African diaspora," the network said.
Combs also created an online marketplace called Empower Global that featured black-owned brands. Its website is still active, but has no products currently listed for sale.

Who is P Diddy and why is he famous?
Combs is among the most influential hip-hop producers of the past three decades.
Also known as Puff Daddy and P Diddy, he built one of hip-hop's biggest empires, blazing a trail with several entities attached to his name.
He is the founder of Bad Boy Records and a three-time Grammy winner who has worked with top-tier artists including Notorious BIG, Mary J Blige, Usher, Lil Kim, Faith Evans and 112.
His latest album, The Love Album - Off The Grid, was released last year, days after Combs was honoured at the MTV VMAs.
It was nominated for best progressive R&B album at February's Grammy Awards, which he did not attend.
