translate English to French: In addition to this internal monitoring, the judicial authorities also have a responsibility to monitor the regulations, instructions, interrogation methods and practices and the provisions concerning the police custody and treatment of persons held for questioning and, to that end, the Attorney-General visits the cells of police stations, usually without prior notice, and systematically releases any person held in custody without legal justification.
À cet effet, le procureur de la République effectue des visites, très souvent inopinées, dans les cellules des commissariats de police et met systématiquement en liberté toute personne dont la garde à vue n'est pas légalement justifiée.
