French authorities have been searching for a group of at least four thieves who were seen heisting precious jewels from the Louvre on Oct. 19.

France’s culture minister says that the Louvre will install streetside anti-ramming and anti-intrusion devices in the next two months

Two more suspects, a man and a woman arrested this week over the jewel heist at the Louvre, have been charged and remanded in custody, prosecutors said.

The precious artifacts snatched from Paris’s Louvre Museum on Sunday include an emerald necklace gifted by Napoleon to his second wife and other priceless crown jewels.

French senators have acknowledged that the Louvre's security is outdated and needs urgent upgrades. On Tuesday, a delegation visited the museum following a recent heist where thieves stole jewels worth 88 million euros in under eight minutes.

High visitor numbers and dwindling funds for overhauls may have made the landmark museum unexpectedly vulnerable.
