Escalating brutality has been at the heart of the long standoff between the citys authorities and its people
When Hong Kongs summer of protests began in June, the city was so shocked by police unleashing 150 canisters of tear gas and using their batons, it helped bring two million people into the streets to demonstrate again and denounce police brutality.
There have been other serious casualties, including a journalist blinded in one eye, and more than 1,100 people have been treated at hospitals for injuries from the protests.
Water cannons laced with dye, beanbags, rubber and sponge-tipped bullets, pepper spray, baton charges and mass arrests have all become common. Gangs of thugs accused of triad links have also attacked demonstrators.
Deepening violence has been central to the long standoff between the citys authorities and its people. Police brutality has fuelled public anger, feeding the protest movement, and as both sides became more entrenched their tactics have escalated.
