A month before an audacious jewelry heist struck the Louvre Museum, Paris’ Natural History Museum saw nearly six kilograms of gold stolen. On Tuesday, a Chinese woman was arrested and charged with the theft.

A Chinese woman has been arrested and charged over a theft of gold worth more than $1 million from Paris’ Natural History Museum, in one of several recent high-profile break-ins targeting French cultural institutions, a prosecutor said on Tuesday, October 21.

The theft took place on September 16, a little over a month before an audacious jewelry heist at the world-famous Louvre Museum on Sunday. At the time, the Natural History Museum’s director said it had been performed by an “extremely professional team.”

A 24-year-old Chinese woman was arrested in Barcelona on September 30 over the Natural History Museum break-in and theft of gold, Paris Prosecutor Laure Beccuau said. The suspect was handed over to French authorities on October 13, and was charged with theft and criminal conspiracy and put in provisional detention the same day.
