R.I. Gen. Laws § 12-9-15
The officer or agent of a demanding state to whom a prisoner may have been delivered following extradition proceedings in another state, or to whom a prisoner may have been delivered after waiving extradition in the other state, and who is passing through this state with a prisoner for the purpose of immediately returning the prisoner to the demanding state may, when necessary, confine the prisoner in the jail of any county or city through which he or she may pass; and the keeper of the jail must receive and safely keep the prisoner until the officer or agent having charge of him or her is ready to proceed on his or her route, the officer or agent, however, being chargeable with the expense of keeping; provided, that the officer or agent shall produce and show to the keeper of the jail satisfactory written evidence of the fact that he or she is actually transporting the prisoner to the demanding state after a requisition by the executive authority of the demanding state, or waiver of the requisition. The person shall not be entitled to demand a new requisition while in this state.
