How did burglars pull off 'the theft of the decade' in 7 minutes at the Louvre?

Thieves wielding power tools robbed the Louvre on Sunday, taking some of France's priceless crown jewels in a brazen, seven-minute heist carried out in broad daylight. Authorities recovered a 19th-century gem-encrusted crown — damaged — near the museum, but the culprits were still at large and the target of a manhunt. Details and analysis by Arthur Brand, art crime detective in Amsterdan, Netherlands and Shirli Sitbon, FRANCE 24 journalist.
