Mariah Carey’s brother is suing the star for defamation following the release of her memoir, multiple outlets report.

According toUSA Today, in court documents filed Wednesday, her brother Morgan, 60, cited a passage fromThe Meaning of MariahCareypertaining to an alleged altercation between him and their father. The singer, 51, wrote in the memoir that a dozen police officers had to split the physical fight at the time.

“Her attempt to falsely characterize plaintiff as equally violent as their father, and her subsequent commentary on police relations with Black people was only the beginning of defendant Mariah Carey’s desperate attempt to vilify plaintiff, play the victim card and curry favor with the Black Lives Matter movement,” reads the complaint, per the outlet.

According toReuters, Morgan also took issue with Carey’s allegation that he tried to extort her for money after she became famous. Additionally, theNew York Post’sPage Sixreported that Morgan claims to have lost a professional project deal because of the way Carey characterized him in her memoir.

A rep for Carey did not immediately respond to PEOPLE’s request for comment.

Describing Carey as “heartless, vicious [and] vindictive,” Alison claimed in her court filing that she’s fallen back into “alcohol abuse” and has become “uncharacteristically tearful” following the book’s September release.

Citing a chapter in Carey’s book, where the singer describes an incident when Alison gave her Valium, tried to “pimp her out and threw a cup of boiling hot tea on her,” Alison’s summons stated that Carey “presented no evidence to substantiate” the story, which Carey’s sister disputed.
