The Paris prosecutor has announced four more arrests in connection with the $102 million jewel heist at the Louvre Museum.

The arrests involve two men and two women from the Paris region, aged 31 to 40.

The prosecutor, Laure Beccuau, did not specify their roles in the October 19 theft.

The stolen jewels, including a diamond-and-emerald necklace given by Napoleon to Empress Marie-Louise and other historical pieces, have not been recovered.

Police have previously arrested other suspected members of the four-person team believed to have carried out the robbery.

Investigating magistrates have filed preliminary charges against three men and one woman arrested in October.
