Jerome Kerviel, the ex-Societe Generale SA trader responsible for a 4.9 billion-euro ($5.5 billion) trading loss, faces a criminal complaint following the release of a covert recording of a prosecutor who cast doubt on the handling of the probe against him, Agence France-Presse said.
The complaint was filed by Chantal de Leiris, a former vice prosecutor who was taped saying “Societe Generale knew” what Kerviel was up to, AFP said, citing unidentified sources. A preliminary investigation was opened Thursday, AFP reports.
Kerviel’s lawyer didn’t immediately respond to a request for comment.
The tape was made last June by Nathalie Le Roy, the police officer who led Kerviel probes in 2008 and 2012. Last year, she told a French judge of her own misgivings about the case.
