But, the United States government will never send warrants or legal notices via email messages. They would be served in person by a U.S. Marshal or other law enforcement officer. Anyone receiving a fake arrest warrant should contact the FBI or the district U.S. Marshals Office. And, if there is any question regarding the authenticity of a warrant, contact your district clerk of court.
