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 €88m (£76m; $102m) - which were taken on 19 October.
Four people have already charged over the heist - three men and a woman, who also live 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.
Details of the Heist: The heist occurred when the gang used a stolen vehicle-mounted lift to gain access to the Galerie d'Apollon via a balcony. They used a disc cutter to break into display cases, stealing items within minutes and escaping on scooters.
One of the stolen items, a crown, was dropped during the escape, but other valuable pieces remain unaccounted for. Heightened security measures are now in place around France's cultural institutions, including transferring some treasures to the Bank of France.
