Another four suspects are now under arrest in the context of the ongoing investigation into the last month's robbery of priceless gems at the famous Paris museum, according to the French judicial authorities.
A pair of males, aged 38 and 39, and two female individuals, 31 and 40 years of age, faced apprehension earlier this week. All are from the Γle-de-France region.
Included in this group is believed to be the final member of a group of four that reportedly executed the daylight heist, according to local news outlets. The additional three suspected thieves were previously detained and formally accused, authorities state.
Police now have as much as 96 hours to conduct interviews. Not a single clue has so far been found of the taken jewelry - worth an estimated 88 million euros (76 million pounds; 102 million dollars) - which were stolen on October 19th.
Four individuals have already been charged concerning the theft - three men and a woman, who similarly reside within the greater Paris.
A woman in her late thirties was indicted in recent weeks with complicity in organised theft and conspiracy to commit crimes with a view to committing a crime.
In a distinct case, a man, aged 37, was accused of robbery and illegal conspiracy.
These two suspects, who have not had their identities disclosed, have denied any involvement.
The robbery occurred when the team of four individuals used a stolen vehicle-mounted mechanical lift to gain access to the Galerie d'Apollon by means of a balcony near the Seine River.
The perpetrators employed a disc cutter to force open showcases which held the precious items.
The perpetrators stayed inside for four minutes and executed their getaway on a pair of scooters positioned externally at 9:38 AM, before transferring to automobiles.
One taken artifact - a royal crown - was dropped during the escape but eight other items of jewellery - including an emerald-and-diamond necklace that Emperor Napoleon presented to his second wife, Marie-Louise of Austria - were stolen.
Officials have revealed that the heist was carried out by petty criminals instead of sophisticated criminal organizations.
Shortly after the theft, it was announced by the Louvre leadership that the single monitoring device observing the Galerie d'Apollon was facing opposite the balcony scaled by the robbers to commit the burglary.
The museum's president has later confessed that the establishment had not fulfilled in its responsibilities, but disputed allegations of security being ignored - saying that from the moment of her appointment in 2021 she had been warning constantly of the requirement for additional resources.
In the wake of the robbery, safeguarding procedures have been enhanced at the nation's cultural landmarks.
The museum has moved a selection of its most valuable gems to the Bank of France after the theft.
