Chris Brown has been sued by a woman who claims that she was sexually assaulted at his California home in February 2017, TMZ reports. The woman, identified as Jane Doe, is being represented by high-profile women’s rights attorney Gloria Allred, who discussed the suit today (May 9) at a press conference outside of the Los Angeles Superior Court, where the suit was filed. In a statement, Allred said the suit alleges “sexual battery, gender violence, a violation of Ralph Civil Rights Act, battery, assault, interference with the exercise of civil rights, intentional infliction of emotional distress and negligence,” according to Rolling Stone.

Jane Doe allegedly attended an afterparty at a recording studio with Brown and Lowell Grissom Jr. (aka Young Lo). She had her phone confiscated, according to Allred. Jane Doe and other women then went to Chris Brown’s house, and, the lawsuit (obtained by Rolling Stone) states, “Brown handed each female guest, including [Jane Doe], a clear pill filled with white powder and instructed them to take it to have a ‘good time.’”

The suit continues, “[Jane Doe] reasonably interpreted Brown’s instruction to have a ‘good time’ at his house to mean that he expected his female guests to later perform sexual acts with him and others while under the influence of these substances. [Jane Doe], who wanted to remain alert and who did not want to perform sexual acts with anyone, did not follow these instructions and declined to consume the pill(s).” Doe claims that she was “scared and intimidated” when she saw that Brown and Grissom were in possession of multiple guns.

At Chris Brown’s house, Brown and Lowell Grissom Jr. allegedly refused to return Jane Doe’s phone to her. When she showed reluctance to take off her clothes or perform sexual acts, the lawsuit claims, another woman referred to as Jane Doe X “violently grabbed Plaintiff by the throat and forced Plaintiff to perform oral sex on Grissom.” Doe X then allegedly forced Doe to give her oral sex. “To compound Plaintiff’s horror, Doe X was menstruating at the time,” the complaint reads. Grissom then allegedly molested Doe with his mouth and hands.

Doe decided to take a shower for health reasons, at which point Grissom allegedly entered the bathroom and molested her again. “Plaintiff fled the bathroom, but Grissom pursued her, and pushed her down onto the bed and raped her,” the complaint states. Grissom finally gave Doe her phone, and while she waited for a rideshare driver to pick her up, Grissom allegedly raped her again, and when it was over, he opened the gate and let her leave. Doe “went to a rape treatment center and to the police where she reported the aforementioned events.”

Allred told the press that it is “one of the most horrific sexual assault cases [she has] ever seen.” She added to the Daily News, “These are very, very serious allegations.”

The LAPD declined to confirm any details in the lawsuit, but Det. Meghan Aguilar confirmed to Pitchfork, “We do not have any open investigations into Chris Brown for a criminal matter.”

Brown’s attorney told TMZ that the lawsuit is a “shakedown” and that “none of these allegations are true.” Grissom’s attorney responded to the lawsuit in a statement to TMZ. “Lowell vehemently denies these false and defaming accusations originated last year, ending with no arrests, no proof, an inconclusive rape kit and after a police investigation—no charges filed.” Grissom’s attorney also called the lawsuit “a blatant attempt at a money grab.”
