Dutch prosecutors said on Tuesday they have raided Uber’s European headquarters in Amsterdam as part of a criminal investigation into whether the company is offering illegal taxi services. A spokeswoman for the Netherlands’ national financial crimes prosecutor said Uber had previously been fined 450,000 euros by the country’s Transport Inspectorate for allowing unlicensed drivers to offer taxi services through its UberPOP ride-sharing service. “The suspicion is that they have continued doing that, despite the fine,” Marieke van der Molen said.
