Louisiana Code of Criminal Procedure Tit. V, Art. 230.2. Probable cause determinations; persons arrested without a warrant and continued in custody; bail

A. A law enforcement officer effecting the arrest of a person without a warrant shall promptly complete an affidavit of probable cause supporting the arrest of the person and submit it to a magistrate. Persons continued or remaining in custody pursuant to an arrest made without a warrant shall be entitled to a determination of probable cause within forty-eight hours of arrest. The probable cause determination shall be made by a magistrate and shall not be an adversary proceeding. The determination may be made without the presence of the defendant and may be made upon affidavits or other written evidence, which may be transmitted to the magistrate by means of facsimile transmission or other electronic means. A magistrate's determination of probable cause hereunder shall not act as a waiver of a person's right to a preliminary examination pursuant to Article 292.
