Four more people have been arrested as part of the investigation into last month's theft of precious jewellery at the Louvre Museum, according to the Paris prosecutor's office.


On a Tuesday, two men aged 38 and 39, and two women aged 31 and 40, were taken into custody, all hailing from the Paris area.


Among them is believed to be the last member of a four-man gang responsible for the high-profile heist, as reported by French media. The other three suspected thieves have already been apprehended and charged.


Police currently have a 96-hour window to question the new detainees. Despite their efforts, no trace of the stolen jewels—valued at €88 million (£76 million; $102 million)—has been found since the incident occurred on October 19, 2025.


Previously, four individuals had already been charged concerning the theft, which includes three men and one woman, all residing in the Paris region. Earlier this month, a 38-year-old woman was charged with complicity in organized theft and criminal conspiracy. Additionally, a 37-year-old man faces charges for theft and criminal conspiracy, both have publicly denied connections to the crime.


The heist took place when the suspects employed a stolen vehicle-mounted mechanical lift to access the Galerie d'Apollon through a balcony adjacent to the River Seine. Using a disc cutter, they breached display cases containing the valuables and made their escape within just four minutes, switching vehicles afterward.


During their hurried exit, one crown was accidentally dropped, but eight other pieces, including a necklace gifted by Napoleon I to Empress Marie-Louise, were stolen. Prosecutor Beccuau described the operation as executed by petty criminals rather than organized professionals.


In light of the incident, Louvre officials have acknowledged security failures; the museum's only camera overlooking the break-in was improperly positioned. Following this incident, the Louvre has reinforced security protocols, including relocating some high-value items to the Bank of France.
