HUNDREDS of anti-government protesters gathered at Hong Kong's International Airport yesterday demonstrating against the police's alleged collusion in a masked-gang attack on protesters.

Last Sunday evening a large group of men dressed in white t-shirts wearing face masks attacked with umbrellas commuters wearing the protesters' signature black T-shirts at Yuen Long metro station. 

Protesters were angered by the Hong Kong police's apparent lack of urgency to deal with the men in white, which some believe were members of the Triad organised crime syndicate.
