Hong Kong Protesters March to Protest Police Use of Force Associated Press Updated at 4:50 a.m. HONG KONG -- A sea of black-shirted protesters, some with bright yellow helmets and masks but many with just backpacks, marched down a major street in central Hong Kong on Sunday in the latest rally in what has become a summer of protest. The march followed a short rally at Chater Garden, a park in the financial district, against the police use of tear gas, rubber bullets and other force to break up a protest the previous Sunday. Police had denied permission to the organizers to march to the Sheung Wan district, where the tear gas was used. In a surprise move, the protesters headed in the opposite direction. Chanting "Add oil," a phrase that roughly means "Keep up the fight," they walked past government and police headquarters. Their destination was unclear. .
