Uber has encountered roadblocks in cities not keen on unregulated taxi services, but it might finally have met its match in the streets of Paris.

Two Uber executives were arrested in Paris Monday for running an illegal taxi company and concealing illegal documents, according to TechCrunch.

The arrested executives — Uber France’s CEO Thibaud Simphal and Uber Europe GM Peirre-Dimitri Gore-Coty — have previously said that Uber would continue operations in the country until a court rules against their service, UberPOP. Although UberPOP has been illegal since late last year, the country has had trouble enforcing the ban since Uber reportedly pays off drivers’ fines and encourages them to continue working.

The arrests come just days after fierce protests plugged up major traffic intersections in Paris. At one point, police in riot gear deployed tear gas on the taxi driver protestors, who say that Uber represents unfair competition.

But even arresting Uber’s executives won’t do much to stop the irreverent service: Simphal and Gore-Coty will probably be released within days, the report said, and France will have to let the case wind through the country’s courts.
