Three men wearing masks entered Christ Jewellery while armed with baseball bats. They made customers and employees get down on the ground while they smashed display cases and took jewelry.
The robbery took about two minutes.
After they were done, the three men ran outside to a waiting Audi that had a huge German flag draped over it and made their getaway, according to the Tagesspiegel newspaper.
"There are a lot of witnesses who need to be heard, and after that we can bring charges -- but that will take time," a spokesman for Berlin police told The Local.
The shop has not released all of the details about what was taken, so it's unclear how lucrative the thieves' haul is at this time.
