NATO experts were able to trace the communications traffic between the two Arab leaders, and so pinpoint Gaddafi to the city of Sirte, where he was murdered on October 20.
NATO jets shot up Gaddafi's convoy, before rebels on the ground dragged Gaddafi from a drain where he was hiding and then subjected him to a violent attack which was videoed.
In another sinister twist to the story, a 22-year-old who was among the group which attacked Gaddafi and who frequently brandished the gun said to have killed him, died in Paris last Monday.
Ben Omran Shaaban was said to have been beaten up by Gaddafi loyalists in July, before being shot twice. He was flown to France for treatment, but died of his injuries.
Sarkozy, who lost the presidential election in May, has continually denied receiving money from Gaddafi.
