Mich. Comp. Laws § 750.192
It shall be lawful for any sheriff, coroner, constable, or other officer of the state of Wisconsin or other person lawfully authorized under the laws of the state of Wisconsin to act as any such officer, having in his or her lawful custody any person or persons, arrested in the state of Wisconsin, under a criminal warrant or process, or under any writ, order, or process in a civil action or proceeding, issued out of or by any court of said state of Wisconsin, or by any officer of said state of Wisconsin, authorized to issue such warrant, writ, process, or order, to convey or transport the prisoner through any portion of the state of Michigan, whenever it shall be necessary or convenient so to do in order to bring the prisoner before any such court or officer of the state of Wisconsin, or to deliver the prisoner to any jailor, or commit the prisoner to any prison of said state of Wisconsin, for any lawful purpose whatsoever. Any such officer of the state of Wisconsin, while in the state of Michigan with any prisoner or prisoners in the officer's custody for the purposes aforesaid, has all the rights and powers in relation to such prisoner or prisoners as would a sheriff of this state.
An officer of this state shall not discharge any such prisoner from custody under writ of habeas corpus or other proceeding brought for that purpose, when it shall be made to appear that the prisoner is in custody as in the preceding paragraph stated. And it shall be a sufficient answer to said writ of habeas corpus or other proceeding, by the officer or person having such custody, that he or she holds the prisoner by virtue of a lawful warrant, writ, process, or order as in the preceding paragraph stated, and he or she shall annex to the answer a copy of the warrant, writ, process, or order under which he or she claims custody of the prisoner.
Any person who shall in any manner aid or assist a prisoner so being conveyed or transported through this state to escape from the officer or person having the prisoner so in lawful custody, or who resists the officer or person while engaged in conveying or transporting the prisoner through this state, is guilty of a misdemeanor punishable by imprisonment for not more than 1 year or a fine of not more than $1,000.00.
