The rallying cry of the protesters, who have trashed public buildings in the Chinese-ruled city, set street fires and thrown petrol bombs at police, has been "five demands, not one less", meaning the withdrawal of the bill make no difference.

Hong Kong leader Carrie Lam had said many times the bill was as good as dead and said that other demands, including universal suffrage and an amnesty for all those charged with rioting, were beyond her control.

Protesters are also calling for her to stand down and for an independent inquiry into perceived police brutality during a long hot summer of running battles on the streets.

"There aren't any big differences between suspension and withdrawal (of the extradition bill)... It's too little, too late," said 27-year-old protester Connie, hours before the bill was withdrawn. "There are still other demands the government needs to meet, especially the problem of police brutality."

Most protesters do not give their full names to avoid being identified.

Police have responded to the violence with water cannon, tear gas, rubber bullets and several live rounds.

Protesters are angry at what they see as Beijing encroaching on the former British colony's "one country, two systems" formula enshrined during the handover in 1997, which permits the city wide-ranging freedoms not available on the mainland such as an independent judiciary.

The extradition bill would have allowed defendants charged with serious crimes to be sent for trial abroad, including to Communist Party-controlled courts in China.

The bill was seen as the latest move by Beijing to erode those freedoms. China has denied these claims and accuses foreign countries of fomenting trouble.

A murder suspect whose case Lam had originally held up as showing the need for the extradition bill walked free on Wednesday as the city's government squabbled with Taiwan over how to handle his potential voluntary surrender to authorities.
