Pro-democracy protesters in Hong Kong have clashed with police for a second night in a row – this time it was near government headquarters.<br /><br />Police used pepper spray to stop the demonstrators from blocking a major road near the office of the territory’s Chief Executive Leung Chun-ying .<br /><br />On the previous night a video of police officers allegedly beating up a member of the pro-democracy Civic Party caused outrage when it went viral.<br /><br />Ken Tsang Kinchiu said he will take legal action against the six police officers who are said to have been reassigned to other duties.<br /><br />However the alleged police brutality appears to have injected a fresh impetus into the three-week long protest calling on Beijing to allow free elections.<br /><br />China rules Hong Kong under a “one country, two systems” formula that accords the city a degree of autonomy and freedom not enjoyed on mainland China. But Beijing has said only candidates screened by a nominating committee will be able to contest a full city-wide vote to choose the next chief executive in 2017.
