(b) Form.
(1) Warrant. A warrant must:
(A) contain the defendants name or, if it is unknown, a name or description by which the defendant can be identified with reasonable certainty;
(B) describe the offense charged in the complaint;
(C) command that the defendant be arrested and brought without unnecessary delay before a magistrate judge or, if none is reasonably available, before a state or local judicial officer; and
(D) be signed by a judge.
(2) Summons. A summons must be in the same form as a warrant except that it must require the defendant to appear before a magistrate judge at a stated time and place.
(c) Execution or Service, and Return.
(1) Whom. Only a marshal or other authorized officer may execute a warrant. Any person authorized to serve a summons in a federal civil action may serve a summons.
(2) Location. A warrant may be executed, or a summons served, within the jurisdiction of the United States or anywhere else a federal statute authorizes an arrest.
(3) Manner.
(A) A warrant is executed by arresting the defendant. Upon arrest, an officer possessing the warrant must show it to the defendant. If the officer does not possess the warrant, the officer must inform the defendant of the warrants existence and of the offense charged and, at the defendants request, must show the warrant to the defendant as soon as possible.
(B) A summons is served on an individual defendant:
(i) by delivering a copy to the defendant personally; or
(ii) by leaving a copy at the defendants residence or usual place of abode with a person of suitable age and discretion residing at that location and by mailing a copy to the defendants last known address.
(C) A summons is served on an organization by delivering a copy to an officer, to a managing or general agent, or to another agent appointed or legally authorized to receive service of process. A copy must also be mailed to the organizations last known address within the district or to its principal place of business elsewhere in the United States.
(4) Return.
(A) After executing a warrant, the officer must return it to the judge before whom the defendant is brought in accordance with Rule
5. At the request of an attorney for the government, an unexecuted warrant must be brought back to and canceled by a magistrate judge or, if none is reasonably available, by a state or local judicial officer.
(B) The person to whom a summons was delivered for service must return it on or before the return day.
(C) At the request of an attorney for the government, a judge may deliver an unexecuted warrant, an unserved summons, or a copy of the warrant or summons to the marshal or other authorized person for execution or service.
