The prosecutor of Bobigny court, in France, opened up an investigation in order "to verify the presence in Le Bourget Airport, on July 20, 2005, of the plane numbered N50BH". This instruction was opened following a complaint deposed in December 2005 by the "Ligue des droits de l'homme" (LDH) NGO ("Human Rights League") and the "International Federation of Human Rights Leagues" (FIDH) NGO on charges of "arbitrary detention", "crime of torture" and "non-respect of the rights of war prisoners". It has as objective to determine if the plane was used to transport CIA prisoners to Guantanamo Bay detainment camp and if the French authorities had knowledge of this stop. However, the lawyer representing the LDH declared that he was surprised that the judicial investigation was only opened on January 20, 2006, and that no verifications had been done before.
