French prosecutors say police detained a 15-year-old on April 25 in connection with a large-scale data breach involving France Titres (ANTS), the agency that handles secure administrative documents. According to the reports, investigators link the suspect to alleged theft of millions of records from ANTS and subsequent online disclosure of large volumes of data. The prosecutors’ case is described as involving computer-crime allegations that follow earlier findings about extensive datasets—reported as up to tens of millions of lines of information—surfacing online.

Both outlets describe the same core allegation: the teenager is suspected of stealing data from the ANTS environment and attempting to sell it. The reports do not provide additional details on the specific breach method, the full contents of the leaked records, or the status of the investigation beyond the detention. The sources also do not specify whether any other suspects are involved or whether authorities have confirmed the integrity of all leaked data. The matter is presented as an active investigation led by French prosecutors.
