New York — Federal authorities arrested a Minnesota man Wednesday after he attempted to impersonate an FBI agent to gain the release of Luigi Mangione from the Metropolitan Detention Center in Brooklyn. Court filings and a criminal complaint state that Mark Anderson, 36, claimed to possess judge-signed paperwork authorizing Mangione's release, displayed a Minnesota driver's license when asked for credentials and told officers he had weapons. Officers searched his bag and found a barbecue fork and a circular steel blade. A complaint was unsealed Thursday and Anderson faces federal impersonation charges.
