Loading "Fight for Hong Kong!" protesters shouted, "five demands, not one less", a reference to demands for universal suffrage and an independent inquiry into police actions, among other things. Police later moved away, leaving protesters, pedestrians and tourists alike to take over the street under the neon lights. Then one water cannon moved in, firing high into the air and down side-streets. Police said protesters later hurled petrol bombs at a police station in Sham Shui Po, northwest of Tsim Sha Tsui, and set fire to shops in Jordan, north along Nathan Road from the harbour. "Some attacked police officers with hard objects and umbrellas," police said in a statement. "Some hurled smoke bombs at MTR (metro) exits."

Reuters witnesses saw two MTR entrances on fire in Mongkok. The number of protesters had grown by the minute earlier in the afternoon, streaming down Nathan Road to the water's edge, in front of the dramatic backdrop of Hong Kong island, but many fled after the tear gas and pepper spray were fired.

Police detained some protesters as they gathered in a rally that had not received official permission. The crowds at the waterfront had largely dispersed after a couple of hours and headed north up Nathan Road, where many luxury brand shops closed their shutters, towards Jordan and Mongkok.

The rallying cry of the protesters was also for the protection of "Muslims, journalists and the people". A police water cannon fired bursts of blue-dyed water at a small group of people outside a Nathan Road mosque during protests last weekend, drawing criticism from some in the Muslim community. There was a large crowd of police outside the mosque on Sunday. Protesters react to tear gas during a confrontation with police.

"Hong Kong people, regardless of our religion ... we come here to say no to our totalitarian government," he told Reuters, adding he wanted to protest peacefully. "I have a little bit of fear ... because our police sometimes they are uncontrollable and they threaten the safety of our people." Vick, 26, a social worker standing outside Chungking Mansions, said he was there in solidarity with South Asians. Hong Kong police in anti-riot gear patrol the streets.

"We would like the government to make the police more just and less violent.” Cindy Chu, 65, a retired nurse, said the police used to be a force for good.

Pro-democracy activists have in recent weeks attacked police with petrol bombs and rocks and slashed one officer in the neck with a knife. Police have responded with tear gas, water cannon, rubber bullets and occasional live rounds, wounding several protesters and a few journalists. Police deny accusations of brutality, saying they have shown restraint in life-threatening situations. There had been a week-long lull in clashes.

Protesters are angry about what they view as creeping Chinese interference in Hong Kong, a former British colony that returned to Chinese rule in 1997 under a "one country, two systems" formula intended to guarantee freedoms not seen on the mainland. China denies meddling. It has accused foreign governments, including the United States and Britain, of stirring up trouble. Financial Secretary Paul Chan said on his blog that the quarter-on-quarter contraction recorded in the three months ending in June had extended into the third quarter. Two successive quarters of contraction are the technical definition of a recession. He said the economy had come under strain on all fronts. "The true remedy was for all quarters in society to stop violence, return to rational dialogue and seek a way out," he said.
