If the requirements of the investigation into a crime or one of the offences falling within the scope of Articles 706-73 and 706-73-1 so require, the liberty and custody judge may, at the request of the public prosecutor, authorise by reasoned order remote access, without the knowledge of the person concerned, to correspondence stored by electronic communications accessible by means of a computer identifier. The data to which access has been granted may be seized and recorded or copied onto any medium.
