A new documentary about the litany of abuse and violence allegations against R&B singer Chris Brown dating back almost two decades promises to unveil the allegations of a new accuser who hasn’t previously spoken about their experience with the star in “Chris Brown: A History of Violence.”

The documentary, set to be released Oct. 27 on Investigation Discovery, will chronicle the singer’s past “all the way back to his troubled childhood” and include the testimony of an unidentified accuser who says they “have not spoken about this matter publicly, but that’s the only way he can be stopped.”

A trailer for the documentary released Monday calls Brown an “iconic, accused, convicted celebrity” and includes an unidentified woman’s voiceover labeling him an “abuser of women, consistently, unapologetically.”

Brown was in 2009 accused of assaulting his then-girlfriend, pop star and billionaire Rihanna, leaving her with physical facial injuries that required she be hospitalized. Brown turned himself in to the police and ultimately accepted a plea deal—he pleaded guilty to felony assault and was sentenced to probation, community service and ordered to attend domestic violence counseling.

Since then, he has been involved in several public fights with other celebrities, has faced lawsuits accusing him of assault and had a restraining order granted against him at the request of an ex-girlfriend, who provided a court with threatening text messages and voicemails.

Representatives for Brown did not immediately respond to Forbes’ request for comment on the new documentary Monday.

“There’s a long list of various different women who have accused Chris Brown of assaulting them. He has an audience full of assault deniers,” one woman claims in the trailer.

The incident with Rihanna has followed Brown throughout his career and the singer has addressed it on multiple occasions, including last year when he said people who “still hate” him for the “mistake” of assaulting Rihanna can kiss his “f***ing ass.” In 2013, he said the night of the assault was the “deepest regret of my life” and in a 2017 documentary said his relationship with Rihanna made him feel like a “monster.” Since then, he’s been followed by more accusations of abuse and assault.

In July, Brown was sued for $50 million after four men accused him and members of his entourage of assault backstage at a concert. An attorney has denied that Brown ever “initiated physical contact with anyone.”

In addition to the Brown documentary, Investigation Discovery has said it will also air a docuseries set for 2025 on the accusations against Sean “Diddy” Combs. The series was announced the day after Diddy was detained following his indictment on sex trafficking and racketeering charges and promises to review “accounts of sexual assault, abusive behaviors and other disturbing claims.”
