A statement released by Hong Kong police warned "rioters" to stop all "illegal acts" and condemned the incident. Investigations are ongoing.
Protesters gathered for an unauthorized march outside the Hong Kong Cultural Centre beginning in Tsim Sha Tsui, about 5km (3 miles) away from Kowloon Tong station.
The police stated that an unauthorized assembly was illegal and called on the protesters to "stop all illegal acts and leave immediately."
