Kim Kardashian was robbed at gunpoint in private residence in central Paris last Sunday night, and the thieves got away with around €9 million in jewels.
While police still haven't tracked down any suspects, they may have made a breakthrough in the hunt for the robbers.
It comes in the form of a jewel that was found by a passerby near the scene of the crime, in Le Madeleine area of the 8th arrondissement of Paris.
The jewel was part of the loot taken from the residence where the US megastar was staying, a police source told L'Express newspaper, confirming other reports in the French media. Although police have not confirmed this claim officially.
The person who found the jewel turned it in to officers after realizing that it could be connected to the case.
Now police are checking to see if there are any fingerprints or if there is any DNA on the jewellery, the source said.
French police are under pressure to find the robbers given the media attention around the case.
Reports say the men spoke French “without an accent” and were of European appearance, aged in their forties. The robbers were disguised as police officers and were also believed to have fled the scene on bicycles.
Five men were believed to have been involved in the robbery, two of who broke into Kardashian's residence and tied her up at gun point.
“The question now is how they got away, because we know they didn't ride their bikes all the way,” the police source told L'Express.
Kim Kardashian returned to the US soon after the robbery.
