if you were threatened with an "arrest warrant" via a phone call or email, read this:
http://news.uscourts.gov/warning-arrest-warrant-scam
"The warrant is phony. A valid warrant would not be served by fax or e-mail. It 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. If there is any question regarding the authenticity of a warrant, contact your district clerk of court."
Definitions, if you need 'em:
* A =summons= is an official notice of a lawsuit. It is given to the person being sued (the defendant).
* A =subpoena= is a court order. It requires someone to come to court, go to a deposition, or give documents or evidence.
* =Papers= is a word sometimes used by scammers, as a scare word. Legal documents can be sent via Certified mail. A courier is not absolutely necessary, although the Sheriff, Constable, or a Bonded Licensed Process Server might be used. Such people will have appropriate ID.
