Thousands of protestors marched to the mainland Chinese government's liaison office in Hong Kong on Sunday, demanding universal suffrage and protesting against Beijing's perceived interference in the territory's recent chief executive election.
Witnesses said police used pepper spray to disperse protestors gathered outside the liaison office after warning them not to break beyond barriers.
The city's seven million people have no say in who becomes their chief executive. Leung Chun-yin, who will take over from incumbent Donald Tsang on July 1, was chosen by an election committee of about 1,200 Hong Kong notables on March 25.
Leung beat a scandal-tainted rival, tycoon and former bureaucrat Henry Tang after a fraught campaign which will intensify pressure on China to keeps its promise to allow Hong Kong a direct leadership election in 2017. Dubbed the "wolf" for what some describe as his steely edge, the tall, trim Leung has been labelled a secret Communist Party cadre - an accusation he denies - by some of staunchly capitalist Hong Kong's media and politicians.
