Some of Hong Kong’s busiest shopping districts have descended into chaos after police used teargas, rubber bullets, pepper spray and water cannon against protesters. Activists hurled bricks and petrol bombs back at the police and started street fires on Sunday as demonstrations entered their 17th week in the city’s most serious political crisis in decades. The protest, which was not sanctioned, was scheduled to start at 3pm local time (0800 BST) in the Causeway Bay shopping district, but dozens of riot police began guarding the area hours before. They stopped and searched a number of young people dressed in black.
