A Minnesota man allegedly impersonated an FBI agent and attempted to free Luigi Mangione, the man accused of assassinating a healthcare executive, from a New York jail, ABC News reported Thursday. Mark Anderson, 36, was charged with impersonating a federal agent after arriving at the Brooklyn Metropolitan Detention Center with a court order to release Mangione, law enforcement sources told ABC News. Anderson reportedly said he had weapons in his bag, which contained a pizza cutter and a barbecue fork, according to ABC News. Mangione is being held at MDC-Brooklyn, awaiting federal and state trials in connection with the December 2024 killing of Brian Thompson, the UnitedHealthcare CEO. Notably, a New York judge dropped terrorism charges against Mangione in September.
