P.R. Laws Ap. tit. 34A, § 1–A, Rule 2.15
Once probable cause is determined, if the judge deems necessary that the minor remains detained, he will issue a detention order.
The detention order shall be issued in writing, in the interest of the minor, with the signature and official title of the issuing judge, addressed to the person in charge of the detention center. It should indicate the offense alleged in the complaint, the docket number thereof, the name of minor and the reason or motive for the detention. It shall also state the date and place of its issuance.
The judge, when issuing a detention order, may examine, among other things, the legal and social record of the minor, if any, and hear the Specialist or Family Relations Technician who may have evaluated or supervised the minor.
The judge ordering the detention of the minor shall be authorized to rescind said order and to order the release of the minor before the complaint is filed.
