HONG KONG (AP) — The Latest on protests in Hong Kong (all times local):

5:45 p.m.

Hong Kong police have fired tear gas at protesters who defied police warnings not to march in a neighborhood where six days earlier a mob apparently targeting demonstrators brutally attacked people in a train station.

Officers in riot gear shot the tear gas Saturday into a crowd of demonstrators who were standing their ground despite appeals from police to end the unsanctioned procession.

The protesters gathered in Yuen Long in a show of defiance against the white-clad assailants who beat dozens of people last Sunday night.

Massive demonstrations began in Hong Kong early last month against an extradition bill that would have allowed suspects to face trial in mainland China, where critics say their rights would be compromised.

Hong Kong police say a man has been arrested for hurting another with a knife in the area where a pro-democracy protest is scheduled to kick off.

A police spokeswoman said Saturday that the man was suspected of common assault.

Protesters have started gathering in Yuen Long, where a mob brutally attacked people in a commuter rail station last Sunday. Saturday's demonstration, which has been banned by police, is intended as a show of defiance against the unknown assailants, who beat dozens of people and wore white in apparent opposition to the protesters' trademark black.

Massive demonstrations began in Hong Kong last month against an extradition bill, which has since been suspended. Protesters' demands include direct elections, the dissolution of the current legislature and an investigation into alleged police brutality.
