HONG KONG—Police launched a late-night operation Nov. 17 to try to flush about 200 protesters out of a university campus on a day of clashes in which an officer was hit in the leg with an arrow and massive barrages of tear gas and water cannons were fired.
Riot police began moving in on one group of protesters outside the campus after issuing an ultimatum for people to leave area. They used tear gas and water cannons on a resistant crowd wearing raincoats and carrying umbrellas.
