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.

See the apparent moment suspected thieves escaped the Louvre after stealing jewels worth more than $100 million.

Veteran detectives who have worked on similar cases said French investigators have a lot of evidence to work with in the Louvre jewel heist.

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.

The theft of French crown jewels overshadowed the robbery of some $100,000 worth of historical coins from a museum dedicated to philosopher Denis Diderot.

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.

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.

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.

The brazen daylight robbery of the Louvre on Sunday has turned into a marketing opportunity for Böcker, a German maker of cranes and elevators whose product was used in the heist.
