A French broadcaster has released video footage it claims shows the dramatic robbery that took place at the Louvre Museum in Paris, where a collection of historic jewels was stolen in broad daylight.

The Louvre — the world’s most-visited museum — remained closed on Monday as authorities continued their investigation into the high-profile theft, which has stunned both the French public and the global art community.

According to the broadcaster, the video appears to capture masked individuals entering a restricted area within the museum and quickly removing display cases before fleeing the scene. French police have not yet verified the authenticity of the footage but confirmed that a forensic review is underway.

Officials described the heist as “well-coordinated and highly professional,” suggesting that the thieves may have had prior knowledge of the museum’s layout and security schedule. Investigators are also examining whether the suspects received inside assistance.

The stolen items — described as priceless jewels with both artistic and historical value — were part of a rotating exhibition featuring rare European artifacts. Authorities have not disclosed the full inventory of missing pieces due to the ongoing investigation.

France’s Ministry of Culture said security procedures at major cultural sites are being reviewed in light of the theft, with particular attention to museums and galleries hosting high-value exhibits.

The Louvre, home to masterpieces such as the Mona Lisa and Venus de Milo, has temporarily closed to assist investigators and reassess its safety systems. Museum officials said they plan to reopen once the review is complete.

The robbery marks one of the most audacious crimes in recent French history, drawing comparisons to past high-stakes art thefts that targeted Europe’s cultural landmarks.
