A peaceful march drawing tens of thousands of anti-government protesters on New Year’s Day spiraled into chaotic scenes as police fired several rounds of tear gas at crowds including families and some protesters threw several petrol bombs. In the Wanchai bar district, some protesters had spray-painted graffiti and smashed cash machines in an HSBC bank branch when plainclothes police moved in, pepper-spraying crowds in a tense face-off, after which several rounds of tear gas were fired. The protesters, many masked and clad in black, regrouped and formed their own line, hurling several petrol bombs and unfurling umbrellas.
