According to a spokeswoman for the Paris prosecutor's office, two French executives of taxi-hailing app Uber have been arrested and are being questioned about "illicit activity" linked to the ride sharing company's service.
Spokeswoman Agnes Thibault-Lecuivre would not identify the two Uber managers detained on Monday.
The notoriously scofflaw company has sparred with the French government over its lowest-cost service, one of the many available options it offers in France.
After last Thursday violent riots in Paris Uber continued to maintain it would keep operating the service until a ruling was handed down by the country's top court.
French officials are upset that Uber pays lower wage rates and social taxes than traditional taxi services.
Uber, as it does in so many markets, argues that the existing taxi system is outdated and is in need of modernization.
It was not clear as of late Monday morning whether the executives would be held overnight or were actually under arrest.
