The Louvre Museum in Paris remains closed as it investigates a brazen heist involving France's priceless crown jewels. Thieves wielding power tools broke into the museum in broad daylight, escaping on scooters with eight extremely valuable items of jewellery.

The robbery occurred on Sunday morning, shortly after the museum opened. Four thieves used a vehicle-mounted mechanical lift to access the Galerie d'Apollon through a first-floor window. Reports indicate that two of the robbers cut through glass panes to enter the museum, threatening guards and evacuating the premises before stealing items from display cases.

A preliminary investigation revealed that one in three rooms in the affected area had no CCTV cameras, raising questions about security protocols during such a critical theft.

This incident has sparked outrage in France, with political leaders decrying the event as an assault on the nation's heritage. Culture Minister Rachida Dati noted that the thieves seemed experienced, with a well-planned escape route.

The stolen items included diadems, a necklace, earrings, and brooches, all from the 19th century, valued at millions. Some items, including Empress Eugénie's crown, were later found near the museum, suggesting a hasty retreat by the robbers.

Over sixty investigators are currently working on the case as authorities analyze CCTV footage from the escape route. The Louvre's closure prompted automatic refunds for visitors with pre-existing reservations, and metal barriers were erected around the premises.

Calls for improved security measures at the Louvre have intensified, as officials emphasize that the safety protocols need urgent revision to prevent similar occurrences in the future.
