Minnesota Man Arrested After Posing as FBI Agent to Free Luigi Mangione from Brooklyn Jail

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.

Mark Anderson, 36, of Mankato, Minnesota, has been charged with impersonating a federal officer following the incident at the Metropolitan Detention Center (MDC). 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.

The 'FBI Agent' with a Pizzeria Toolkit

According to the criminal complaint filed in the Eastern District of New York, the incident unfolded at approximately 6:50 p.m. on 28 January. 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.

He claimed to be in possession of paperwork 'signed by a judge that authorised the immediate release of a specific inmate. While the court documents did not explicitly name the prisoner Anderson was seeking to free, law enforcement officials have since confirmed to multiple news outlets that the target was indeed Mangione.

The charade quickly unravelled when officers asked for Anderson's federal credentials. Rather than producing a badge or government ID, the Minnesota native reportedly presented a standard state driver's licence.

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.

Upon searching Anderson's bag, officers did not find firearms. Instead, they discovered a large barbecue fork and a circular steel blade resembling a small pizza cutter wheel.

It was later revealed that Anderson had recently been working at a pizzeria in the Bronx after a previous job opportunity had fallen through.

A Critical Moment in the Mangione Trial

The audacity of the attempted jailbreak comes at a particularly sensitive time for Mangione's legal proceedings. Just hours before Anderson's arrest, the Manhattan District Attorney's office had formally requested a 1 July trial date for the state-level murder charges against him.

Mangione is currently facing a dual-track prosecution. In addition to the state charges, he faces federal counts related to the targeted killing of Brian Thompson outside a Manhattan hotel. A federal judge is expected to rule shortly on whether prosecutors may seek the death penalty in his case.

The Metropolitan Detention Center, where Mangione is held, is no stranger to high-profile inmates. Its current population includes former Venezuelan President Nicolás Maduro, and it has previously housed figures such as Sam Bankman-Fried and Sean 'Diddy' Combs.

However, an attempt to breach the facility's security using a pizza cutter and a Minnesota driver's licence is considered an unprecedented, if amateurish, occurrence.

Background of the Suspect

Multiple media outlets found Mark Anderson has a history of legal and personal struggles. ABC News reported public records indicate that Anderson has multiple open cases in the Bronx. His lawyer, Michael Weil, proposed that the court allow his client to seek mental health treatment saying that it was 'apparent Mr. Anderson has other problems.'

Following his arrest on Wednesday, Anderson appeared in Brooklyn federal court on Thursday afternoon. He was ordered to be held without bail until his next court date in 12 February and, in a stroke of irony, is now being detained in the very same facility from which he allegedly tried to spring Mangione.

If convicted of impersonating a federal officer, Anderson faces a maximum of three years in prison. Meanwhile, Mangione remains in custody as he prepares for a series of hearings that will determine his fate in one of the most publicised American murder trials of the decade.
