Paris prosecutor says apprehended Louvre heist suspects have spoken, as $102M crown jewels remain missing

"I want to remain hopeful that [the jewels] will be found and they can be brought back to the Louvre, and more broadly to the nation", Beccuau said.

There is no evidence that the robbery was an inside job, according to Beccuau. Authorities made the two arrests on Saturday, with one of the men attempting to board a plane to Algeria. Beccuau said that the suspects in custody have at least in part recognized their involvement in the heist, Reuters reported.

The thieves escaped with a total of eight objects, including a sapphire diadem, necklace and single earring from a set linked to 19th-century queens Marie-Amélie and Hortense. They also stole an emerald necklace and earrings tied to Empress Marie-Louise, Napoleon Bonaparte's second wife, and a reliquary brooch. Empress Eugénie's diamond diadem and her large corsage-bow brooch - an imperial ensemble of rare craftsmanship - were also part of the loot.

Eugénie's emerald-set imperial crown with more than 1,300 diamonds was later found outside the museum, damaged but recoverable.
