According to the channel's information, the detained individual is allegedly a member of the "Louvre commandos" and may have been directly involved in the crime.
After interrogating the suspect, two of his alleged accomplices were charged and taken into custody.
According to La Chaîne Info, four people were detained on October 29 as part of the investigation into the Louvre robbery, while RTL reports five new arrests.
Paris prosecutor Laure Beccu confirmed that the investigation is considering the possibility of assistance from a museum employee.
Earlier, it was reported that two suspects in the theft of the jewels had been detained.
Recall that the robbery occurred early in the morning on October 19.
As a result, nine pieces of 19th-century jewelry were stolen, including the crown of Empress Eugenie, which was damaged during the criminals' escape (the crown was later found). The list of stolen items also includes a necklace made of emeralds and diamonds, gifted by Napoleon to his wife Empress Marie-Louise, as well as a diadem adorned with nearly 2,000 diamonds that belonged to Empress Eugenie, and a necklace once owned by Maria Amalia, the last queen of France, featuring 8 sapphires and 631 diamonds.
