Chinese President Hu Jintao has sworn in Hong Kong's new leader, amid demonstrations in the city.
Although hundreds of police formed a solid ring fence to ensure the isolated protests were kept out of sight and earshot, one demonstrator managed to gain access, standing and heckling Hu as he spoke.
Election committee member, Ken Tsang shouted slogans, demanding an end of one-party rule in China and the vindication of the bloody crackdown at Tiananmen Square in 1989, before being wrestled away by several security personnel.
Hu expressed China's confidence in Hong Kong's role as a free, law-abiding society, though in a sign of Beijing's anxiety over recent tensions, he appealed for unity and called on the administration of Leung Chun-ying, who was sworn in for a five-year term, to heed the recent social schisms.
"While we recognise Hong Kong's achievements 15 years after the handover, we must also be conscious of the deep disagreements and problems in Hong Kong society," Hu said.
Outside the venue, masses of Hong Kong police and high barricades smothered attempts by protesters to approach, with several demonstrators being taken away in a police van.
