La. Stat. tit. 15 § 707
All the sheriffs, jailers, prison keepers, and their deputies to whom any person shall be sent or committed by United States marshals or their deputies, under the authority of the United States, whether on civil or criminal process, or upon any process or warrant which may be issued by the President of the United States, or those to whom he may delegate authority for any cause whatever under the law of the United States, shall take the prisoners into custody and keep them safely until their discharge by due course of law.
Any sheriff, jailer or prison keeper violating this Section shall be liable to the same penalties and the parties aggrieved shall be entitled to the same remedies as if the prisoners had been committed to their custody by virtue of legal process issued under the authority of Louisiana.
The sheriffs or jailers may contract with the U.S. Marshal of his district for the payment of a minimum rate of one dollar per day for the keeping of each federal prisoner. The sheriffs may use the funds for the proper care and safekeeping of the federal prisoners and to pay any expenses incurred in connection with their office or jail.
