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.

The Louvre Museum heist was a classic case of German efficiency. That at least is how a German freight lift manufacturer jokingly portrayed it in an ad.

A daring daylight jewellery heist at the Louvre Museum has inadvertently provided an unexpected boost for a German manufacturer, after images of their freight lift, used by the thieves, went viral. Böcker Maschinenwerke GmbH, the German firm behind the equipment, is now experiencing a surge in attention following the audacious robbery.

To the world, the news was astonishing, bordering on incomprehensible: Four Parisians were up and about early on a Sunday morning (well, 9:30). And not only that—they had robbed the Louvre.

Investigators have collected more than 150 trace samples, including fingerprints, bits of DNA and other silent evidence, from the scene of the Louvre 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.”

Investigators hunting the gang behind the heist have also found traces of DNA samples in a helmet and gloves, prosecutors confirmed to NBC News.

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

It was, in nearly every way, an ordinary photo distributed by The Associated Press to news media outlets. It showed three policemen leaning against a silver car parked in the courtyard of the Louvre Museum in Paris just hours after the brazen theft of a collection of French crown jewels on Sunday.

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.

"I saw one of the criminals turn around with something that looked to me like a chainsaw, then I yelled at my colleagues to get out," she recalled. She shouted a second time that it was a robbery and that they should run.
