R.I. Gen. Laws § 12-16-8: Receiving custody of witness from another state.

If the certificate recommends that the witness be taken into immediate custody and delivered to an officer of this state to assure his or her attendance in this state, the judge may direct that the witness be immediately brought before him or her; and the judge, being satisfied of the desirability of the custody and delivery, for which determination the certificate shall be prima facie proof, may order that the witness be immediately taken into custody and delivered to an officer of this state, which order shall be sufficient authority to the officer to take the witness into custody and hold him or her unless and until he or she may be released by bail, recognizance, or order of the judge issuing the certificate.
