Minnesota Man Charged After Allegedly Posing as FBI Agent to Free Luigi Mangione from NYC Jail
A Minnesota man now faces federal charges after allegedly trying to break Luigi Mangione out of a New York City jail by impersonating an FBI agent — in a bizarre episode that has captivated national attention.
Authorities say 36-year-old Mark Anderson arrived at Brooklyn’s Metropolitan Detention Center on Wednesday, claiming he carried a judge-signed court order to release Mangione, the 27-year-old accused in the high-profile December 2024 killing of UnitedHealthcare CEO Brian Thompson.
When Bureau of Prisons staff asked Anderson for credentials, he reportedly produced only his Minnesota driver’s license and insisted he had weapons in his bag. A search revealed a barbecue fork and a rounded blade resembling a pizza cutter, according to court records.
Anderson was arrested on charges of impersonating an FBI agent after throwing documents at officers and failing to present valid identification.

“This kind of deception — posing as a federal agent to access a secure detention facility — is dangerous and unlawful,” a federal law enforcement official said, underscoring the gravity of the incident.
Mangione remains in federal custody pending multiple legal proceedings, including a federal court conference scheduled for Friday where a judge may decide whether prosecutors can seek the death penalty.
The case has drawn intense public scrutiny, with Mangione’s supporters clashing with critics over the motives behind his alleged killing of Thompson.
Anderson is expected to appear in federal court in Brooklyn later Thursday, where formal arraignment is set.
What happens next could include prosecutors seeking detention and preparing for trial on the impersonation charges.
