Authorities in France are on the hunt for two individuals who broke into a museum housing masterpieces by the renowned French impressionist Auguste Renoir. The incident occurred early Tuesday morning. The thieves stole four artworks, though they dropped one while escaping, according to the mayor of Cagnes-sur-Mer.

Spotted thanks to the town’s video surveillance cameras, the two individuals fled, abandoning one of the stolen paintings as they ran, stated Bryan Masson, the town’s mayor. His office approximated the value of the stolen paintings at 9 million euros, which is about $10 million. It’s unclear if this estimate includes all four paintings initially taken or just the three that remain missing. Mayor Masson didn’t specify which paintings were stolen.

According to a statement on Masson’s Facebook page, the museum’s alarm alerted authorities at 5:48 a.m., and police arrived on the scene within five minutes. An image captured shows a police officer stationed at the entrance of the Musee Renoir after the theft occurred.

Since this morning, both the municipal and national police have been deployed to the site, Masson added. The perpetrators are being actively sought, and the investigation is ongoing. He emphasized the gravity of the situation by stating, Attacking the Renoir Museum is attacking a part of the history and heritage of Cagnes-sur-Mer. These events are particularly serious.

Masson also highlighted the need for a comprehensive plan to secure museums and protect artworks. We will dedicate all necessary resources to better protect this heritage, which belongs to all the residents of Cagnes, he committed.
