Four more people have been arrested as part of the investigation into last month's theft of precious jewellery at the Louvre Museum, the Paris prosecutor's office says.
Two men, aged 38 and 39, and two women, aged 31 and 40, were arrested on Tuesday. They are all from the Paris region.
Among them is thought to be the last member of a four-man gang that allegedly carried out the daylight heist, according to French media. The other three suspected thieves have already been arrested and charged, officials say.
Police now have up to 96 hours to question them. No trace has so far been found of the stolen jewels - worth €88 million (£76 million; $102 million) - which were taken on October 19.
Four people have already faced charges in connection with the heist - three men and a woman, who also reside in the Paris region. A 38-year-old woman was charged earlier this month with complicity in organised theft and criminal conspiracy with a view to committing a crime.
Separately, a man, aged 37, was charged with theft and criminal conspiracy. These two suspects, who have not been named publicly, have denied any involvement.
Meanwhile, investigations revealed that the robbery was executed by petty criminals rather than organised professionals. The thieves gained access to the Galerie d'Apollon via a mechanical lift and used a disc cutter to breach display cases housing the jewellery.
The heist has prompted heightened security measures around France's cultural institutions, with the Louvre transferring some of its most valuable items to the Bank of France following the incident.
