In a bizarre twist to a case that has already gripped the American public, a Minnesota man was arrested on Wednesday evening after allegedly posing as a federal agent in a failed attempt to liberate Luigi Mangione from a high-security Brooklyn jail. According to court filings, Anderson arrived at the facility claiming to be an FBI agent on a mission to secure the release of Mangione, the man accused of assassinating UnitedHealthcare CEO Brian Thompson in December 2024. Anderson allegedly approached the intake area of the notorious Brooklyn lockup and informed uniformed Bureau of Prisons (BOP) officers that he was a federal agent. When further questioned, Anderson allegedly threw a stack of documents at the officers—papers that an FBI agent later described as 'claims against the U.S. Department of Justice'—and claimed he was armed. Following his arrest on Wednesday, Anderson appeared in Brooklyn federal court on Thursday afternoon.
