Michigan Compiled Laws, Chapter 780. Criminal Procedure § 780.42

Sec. 2. (1) If a person who has been charged with crime in another state and released from custody prior to final judgment, including the final disposition of any appeal, is alleged to have violated the terms and conditions of his release, and is present in this state, a designated agent of the court, judge or magistrate which authorized the release may request the issuance of a warrant for the arrest of the person and an order authorizing his return to the demanding court, judge or magistrate. Before the warrant is issued, the designated agent shall file, with a judicial officer of this state having authority under the laws of this state to issue warrants for the arrest of persons charged with crime, the following documents:

(2) Upon initially determining that the affiant is a designated agent of the demanding court, judge or magistrate, and that there is probable cause for believing that the person whose removal is sought has violated the terms or conditions of his release, the judicial officer shall issue a warrant to a law enforcement officer of this state for the person's arrest.

(3) The judicial officer shall notify the prosecuting attorney of his action and shall direct him to investigate the case to ascertain the validity of the affidavits and documents required by subsection (1) and the identity and authority of the affiant.
