It's the latest setback for the San Francisco-based company as its overseas expansion meets multiple legal and regulatory challenges. Uber has also faced other challenges in greater China, where police this year paid visits to its offices in the mainland cities of Chengdu and Guangzhou as part of a widening investigation into its operations. In a statement, Uber spokesman Harold Li said it "ensures that all rides are covered by insurance, and all drivers on the platform undergo an extensive background check."
The company said it stands by its drivers "100 percent" and welcomed the opportunity to work with the authorities on updating regulations. Uber has had major conflicts with taxi operators in cities like Mexico City, Johannesburg, and Paris.
The ridehailing company is also one of the issues that the potential 2016 US presidential candidates are talking about on the campaign trail.
