Rule 3.3. Execution and Return of Warrant;  Defective Warrants

(a) By Whom The warrant is directed to, and may be executed by, all peace officers in Arizona.

(b) Manner of Execution A warrant is executed by arresting the defendant named in the warrant. The officer does not need to possess the warrant when the arrest is made, but the officer must show the warrant to the defendant as soon as possible if the defendant asks to see it. If the officer does not have the warrant when the arrest is made, the officer must inform the defendant of the charged or alleged offense and the fact that a warrant has been issued.

(c) Return Except for pre-charge arrest warrants, the warrant must be returned either to the magistrate who issued it or to the magistrate at the initial appearance. Pre-charge arrest warrants must be returned to the issuing court as provided in Rule 2.7.

(d) Defective Form A defect in form does not invalidate the warrant or require the release of a person in custody. A magistrate may amend a warrant to correct a defect in form.
