Hong Kong: A cop was struck in the leg by an arrow shot by a Hong Kong activist on Sunday, the city’s force said, as fierce clashes raged at a university which has become a fulcrum of pro-democracy protests. Images showed the arrow embedded in the calf of the police officer, who was working with the force’s media liasion team at the Hong Kong Polytechnic University (PolyU), the scene of fierce clashes. A statement said he was taken to hospital in "a conscious state".

Police deployed water cannon and tear gas against protesters occupying the campus in the Hung Hom area of Kowloon, now a key battleground as the demonstrators fight to keep a stranglehold on the Cross-Harbour Tunnel nearby, blocked since Tuesday. Activists have vowed to "squeeze the economy" as the increasingly divided city reels from one of the worst weeks of violence in the months-long crisis. Protests have swept the global financial hub since June as many in the city have vented fury at eroding freedoms under Chinese rule.
