Hong Kong riot police fire tear gas near university campus

Protesters clash with police at the Polytechnic University of Hong Kong in Hong Kong

HONG KONG (Reuters) - Hong Kong riot police fired volleys of tear gas at protesters emerging from a university campus on Sunday, according to a Reuters witness, as overnight violence restarted.

Hours earlier, police tear gas forced hundreds of protesters, some lobbing petrol bombs, to retreat behind make-shift fortifications at the Hong Kong Polytechnic University in some of the most dramatic scenes since protests began more than five months ago.
