Multiple inmates were stabbed during a violent brawl at the Metropolitan Detention Center (MDC) in Brooklyn, New York, on the morning of September 6. The incident took place at a federal jail that currently holds high-profile detainees, including Luigi Mangione, the CEO of UnitedHealthcare accused of killing Brian Thompson in 2024, and Nicolás Maduro, the former president of Venezuela. According to federal officials, several inmates suffered injuries serious enough to require medical care outside the facility, while others received treatment on-site. However, the exact number of people involved in the fight, the number of those injured, and the nature of the injuries remain unclear. Sources indicated that the brawl occurred between members of the Trinitarios gang and another gang on the seventh floor of the jail’s west building, with at least 20 individuals participating. The New York Daily News first reported on the incident, describing it as gang-related. A spokesperson for the Federal Bureau of Prisons, Donald Murphy, confirmed that the situation was contained by jail staff, with no injuries reported among employees or the public. The incident is currently under investigation, and authorities are working to determine the full extent of what occurred. MDC Brooklyn has become known for housing high-profile inmates. Luigi Mangione is awaiting sentencing for the murder of Brian Thompson, the CEO of UnitedHealthcare, which he admitted to in court. He stated that he understood his actions would cause Thompson to fear for his life. Meanwhile, Nicolás Maduro and his wife, Cilia Flores, are awaiting trial on drug trafficking charges after being captured in January. They have pleaded not guilty to charges related to an alleged conspiracy to transport cocaine to the United States. The jail has a documented history of violence. In February 2025, Karl Jordan Jr., a man previously convicted and later acquitted of the 2002 murder of rapper Jam Master Jay, survived a stabbing attack. In September 2024, the Justice Department announced charges against nine inmates in five separate cases involving violence at MDC Brooklyn, including the murders of Uriel Whyte and Edwin Cordero. United States Attorney Breon Peace emphasized that violence would not be tolerated in federal facilities and warned that those involved in criminal activity behind bars would face consequences.
