Man arrested after posing as FBI agent with pizza cutter to free Luigi Mangione

A man was arrested Wednesday night after prosecutors say he pretended to be an FBI agent and attempted to break accused UnitedHealthcare CEO killer Luigi Mangione out of the Metropolitan Detention Center in Brooklyn. Federal prosecutors said Mark Anderson showed up at the MDC claiming to have a court order to free Mangione and, when Bureau of Prisons officials asked him to identify himself, produced a Minnesota driver’s license and said he had weapons in his backpack.

According to a criminal complaint, Anderson “displayed and threw at the BOP officers numerous documents.” Bureau of Prisons staff found a pizza cutter and a barbecue fork in his bag; federal prosecutors included a photo of those items in the complaint. Mangione remains jailed at the MDC while awaiting trial on charges that he killed UnitedHealthcare CEO Brian Thompson in December 2024, Bureau of Prisons records show.

He has pleaded not guilty to the charges in both the federal and Manhattan cases. Mangione is due in federal court in Manhattan on Friday morning, when a judge may rule on issues including whether he will face the death penalty and whether prosecutors can show jurors evidence recovered at his arrest, such as a 9 mm handgun and a journal.

Jury selection on the federal charges is scheduled for September; the Manhattan DA has asked for a July trial date for its murder case.
