Police fired tear gas and modified shotgun rounds in Hong Kong on Friday night as protests continued despite a pledge by the Hong Kong authorities to drop a controversial planned extradition bill.

Protesters besieged a police station and a nearby underground station, demanding surveillance footage of a police raid last weekend amid rumours of a cover-up of the death of protester.

Angry crowds surrounded the Prince Edward underground station in Kowloon, using wooden boards and umbrellas to form a line, and chanting “Black cops, return life” and “Tell us the truth”. After police fired tear gas and “beanbag round” shotgun shells, protesters blocked the road by setting light to rubbish bins and stacks of cardboard.
