What makes me a bit suspect is that only one news source has published this. If it was more substantiated, I would think many news agencies would be on top of it
The author of the Le Figaro article - Fabrice Amedeo, has demonstrated a number of times that he has some sources close to the investigation. It has previously been commented on in Part 1 of this thread.
When the smoke clears, there may well be some substance to what has been reported, but until then I wouldn't want to draw any conclusions.
