Mass protests in Hong Kong are being rapidly dispersed by hundreds of riot police, using tear gas and shields.

Protesters are making a last stand on Harcourt Road outside the Legislative Council building, which they unexpectedly occupied on Monday.

Police have been seen outside the entrance of the government building, indicating it may no longer be in protester control.

The speed with which protesters have been cleared in comparison to the heated protests on June 12 is staggering.

Once again, the police are raising the black flag, warning the remaining demonstrators that they'll be launching tear gas soon.
