Rioters went on another wild rampage across Hong Kong on Sunday, seriously wounding a police officer on the 19th consecutive weekend of indiscriminate violence. In what's seen as one of the most brutal attacks on a law enforcer, a police officer was slashed in the neck with a box cutter by masked protesters in Kwun Tong. He was bleeding profusely and was taken to United Christian Hospital. Two suspects were arrested on the spot.
