A pizzeria worker posing as an FBI agent and armed with a pie cutter is facing federal charges after authorities say he tried to bust Luigi Mangione out of jail, according to multiple news reports.

Mark Anderson of Mankato, Minnesota, was charged on Thursday, Jan. 29, with impersonating an FBI agent after he showed up to a federal jail in New York City the night before and said he had a court order to release Mangione, according to a criminal complaint obtained by NBC News and the Associated Press.

When officials at the Metropolitan Detention Center in Brooklyn asked to see Anderson’s FBI credentials, the complaint says he produced a Minnesota driver’s license and said he was armed, the agencies reported.

Officers then searched Anderson’s bag and found a circular steel blade that looked like a small pizza cutter wheel, in addition to a barbecue fork, the complaint said.

USA TODAY is working to obtain the complaint, which is not yet available in online records. The complaint does not identify the inmate whom Anderson was trying to help but a law enforcement source told AP and NBC News that it was Mangione.
