Protesters donning hard-hats, masks and other gear could be seen hurling bricks at the Tsim Sha Tsui Police Station in Mong Kok province, while others set fire to garbage cans and other debris in the streets, according to SCMP.  

Protesters could be seen hurling bricks at the Mong Kok province police station, while others vandalized walls, vehicles and lamp posts.  

A day after thousands of civil servants took to the streets in Central to urge authorities to give in to protesters' demands, people gathered on Saturday for an approved rally in the shopping hub of Mong Kok, but which soon splintered off into different directions, ending in clashes in Mong Kok and Tsim Sha Tsui as police used tear gas. 

Outside Tsim Sha Tsui Police Station, some had hurled bricks into its car park, while others vandalised vehicles and lamp posts. The force said it had issued a warning for the crowd to leave before firing rounds of tear gas.
