A Minnesota man armed with a BBQ fork and a pizza cutter was arrested at a Brooklyn jail Wednesday after allegedly impersonating an FBI agent in an attempt to bust high-profile inmate Luigi Mangione out of custody. While the complaint does not name the inmate Anderson sought to free, a law enforcement source told Fox News it was Mangione, the man accused of killing UnitedHealthcare CEO Brian Thompson in December 2024. At about 6:50 p.m., Anderson allegedly approached the intake area and told uniformed Bureau of Prisons officers he was an FBI agent carrying paperwork "signed by a judge." Officers detained Anderson on the spot and searched his backpack, where they found a large barbecue-type fork and a pizza cutter.
