HONG KONG  – Hong Kong police fired tear gas on Tuesday in the Central financial district, over the harbour in Mong Kok and at universities to break up pro-democracy protests which they said were leading the city to the “brink of total breakdown”.

The clashes came a day after police shot a protester at close range and a man was doused with petrol and set on fire in some of the worst violence in the Chinese-ruled city in decades.

A flash mob of more than 1,000 protesters, many wearing office clothes and face masks, rallied in Central for a second day during lunch hour, blocking roads below some of the city’s tallest skyscrapers and most expensive real estate.

After they had dispersed, police fired tear gas at the remaining protesters on old, narrow Pedder Street. Police made more than a dozen arrests, many pinned up on the pavement against the wall of luxury jeweller Tiffany & Co.

“Our society has been pushed to the brink of a total breakdown,” a police spokesman told a briefing, referring to the last two days of violence in the former British colony.
