In June 2019 Renault published that in an internal audit they had uncovered 11 million euros in questionable expenses by Ghosn, which was followed by the French state opening its own investigation into his actions. Prosecutors in the district of Nanterre west of Paris stated that anti-fraud police had searched his residence in the town of L'Étang-la-Ville for evidence. In July Renault's headquarters in Boulogne-Billancourt were searched by 20 police personnel in relation to this case. July also saw Carlos Ghosn take action against French mass-media for libel.
