Paris Prosecutor, Lauce Beccuau stated that the treasures looted from the Louvre Museum last weekend are estimated to be worth more than $100 million (about RM480 million).
Beccuau explained that the theft not only has a financial impact, but also affects the historical heritage of France.
The robbery reportedly took place last Sunday, and the thieves only needed seven minutes to make off with the priceless royal jewels.
Prosecutors said authorities are currently analyzing fingerprints of four individuals believed to be involved in the robbery.
Meanwhile, authorities also believe the robbery was carried out by an organized crime group who climbed onto the ladder of a truck to enter the museum.
Detectives are currently examining camera footage around the Louvre and the main highway out of Paris to track down the suspect who is believed to have fled on a scooter.
The robbery incident has sparked heated discussions about the level of security at museums in France, especially after two other institutions were targeted last month.
A report by the French Court of Appeal from 2019 to 2024 revealed persistent delays in efforts to improve security at the Louvre, where only a quarter of one wing is equipped with a video surveillance system.
In January, Louvre President Laurence des Cars also warned Culture Minister Rachida Dati about the museum's dilapidated state and demanded funding for major renovations.
