A German company inadvertently embroiled in the Louvre Museum heist after one of its lifts was used in the theft is making the most of its free publicity - by launching a new advertising campaign.

A separate post from the social media influencer Ian Miles Cheong, viewed over 90,000 times, reads, “The man in the fedora, who looks like he came out of a detective film noir from the 1940s is an actual French police detective who’s investigating the theft of the Crown Jewels at the Louvre. Pure aesthetic.”

Master jeweler Stephen Portier said the Louvre robbers might recut the stolen gems, which would significantly decrease their value.

Thieves used a stolen truck-mounted moving lift to scale the Louvre and steal royal jewels worth over $100 million in a lightning-fast Paris heist.

Meanwhile, the Louvre’s director, Laurence des Cars, is set to make a much-anticipated appearance in front of France’s Senate Culture Committee to answer questions regarding the museum's security and what went wrong on Sunday when nine pieces were swiped from the museum’s Apollo Gallery.

About 100 investigators are now involved in the police hunt for the gems and heist suspects​, said prosecutor Laure Beccuau, whose office is leading the investigation.

Fox News senior foreign affairs correspondent Greg Palkot reports from Paris, France on new details in the daring daylight Louvre jewel heist and Interpol’s role in tracking the suspects.

Does a photo show a well-dressed French detective working the case of the Crown Jewels stolen from the Louvre? No, that's not true: The original poster later said it was a "fantasy version" she did not regret posting.
