Four more people have been arrested in connection with the brazen jewel heist at the Louvre Museum in October.

Two men and two women from the Paris region were taken into custody this morning,adding to the three men already in custody.

An alleged ‘fourth man’ in the robbery,who had been at large,was arrested in Paris today,an insider said.

The man,from the northern Paris suburb of Aubervilliers,was ‘well known to police’.

The source added: ‘He is being held under suspicion of organised robbery and criminal conspiracy.’

The break-in saw items worth more than £76 million stolen,including gem-studded royal tiaras,necklaces and earrings dating to the 19th century.

The daytime four-minute heist,which stunned France,took place during regular visiting hours on October 19.

The thieves,posing as workers,used a truck-mounted device to reach the second floor before smashing through a window with power tools.

Squeezing into the lavish Apollo Gallery,they cut through reinforced glass display cases and grabbed eight jewels before fleeing on scooters.

Prosecutors raced to arrest those involved in the robbery,with experts fearful that the priceless gems and rare metals would be melted and sold.

Around 150 pieces of DNA evidence led to the arrest of two men who had entered the museum.

One of the men,named only as Ayed G,was about to board a flight to Algeria when he was arrested.

Abdoulaye N,who was reportedly trying to get to Mali,was also brought into custody.

A third man,Slimane K,is suspected of having driven one of the two getaway scooters.

The unnamed fourth suspect drove the second scooter.

The gallery,known in French as the Galerie d’Apollon,remains closed,according to the Louvre website.

The remaining jewellery was moved into a secure vault 85 feet below the Bank of France.
