Uber has been told to immediately suspend its ride-sharing services in Colombia, the industry and commerce authority announced Friday, citing unfair competition laws.
The US tech giant has around two million active users in the country, and roughly 88,000 drivers.
The ruling, which is subject to an appeal, follows a lawsuit by a group of taxi drivers who accuse the company of unfair business practices.
The head of the Industry and Commerce department -- which regulates the market -- said that the company must cease operation immediately, citing "unfair competition" and a "significant advantage" over older and more traditional taxi services.
The "effects (of the measure) are immediately fulfilled," they added.
In a statement, the US firm regretted and rejected the ruling, which it "appealed immediately."
