UFC Legend BJ Penn Arrested in Shocking Brawl, Claims Elderly Woman Is ‘Fake Mother’

Former UFC champion BJ Penn has sparked a massive MMA scandal after his arrest in Hilo, Hawaii, on May 25, 2025, for allegedly assaulting a 79-year-old woman he bizarrely claims is impersonating his mother, Lorraine Shin. The UFC Hall of Famer, 46, was arrested twice over the weekend on charges of “abuse of a family or household member” following disturbing incidents. Penn shared a chilling Instagram video showing police dragging him from his bed, accusing him of harassment after he allegedly took the woman’s mail and shined a flashlight in her eyes. He was released on $2,000 bail.

Penn’s mother filed for a restraining order, claiming he suffers from Capgras syndrome, a rare disorder where someone believes loved ones are impostors. She alleges “extreme psychological abuse,” stating Penn believes she “killed his family” to steal assets. Penn has made erratic social media posts, accusing his mother and brothers of being replaced by frauds attempting to seize his family’s fortune. Fans are stunned, with many expressing concern over Penn’s mental health, speculating about CTE from his 18-year UFC career, where he won lightweight and welterweight titles.

The MMA community is reeling, with fighters like Brendan Schaub voicing worry. Penn’s history of legal troubles, including DUI arrests and bar brawls, adds to the tragedy of this once-dominant fighter’s fall. As Penn is due in court on June 10, fans hope he gets the help he needs. Will this scandal mark the end of his tumultuous post-fighting career?
