Uber's offices in Hong Kong have been raided by police following the arrest of five drivers in the country.
An operation cracking down on illegal taxis lead to the arrests, AP reports citing a police statement. The drivers are being held on suspicion of illegally carrying passengers and driving without insurance, it said.
It's just the latest example of authorities focusing their attention on the controversial billion-dollar startup which lets people order cars through just the tap of a mobile app. Uber's offices in China and Australia have been raided in recent months.
In June Uber bosses in France were questioned by French police. Rioting by French taxi drivers broke out amid protests over the company which the country's interior minister Bernard Cazeneuve and President Francois Hollande called to be banned.
Uber had not responded to a request for comment at the time of publication.
