HONG KONG — Police in Hong Kong fired tear gas Saturday at protesters who defied authorities' warnings not to march in a neighborhood where six days earlier a mob apparently targeting demonstrators brutally attacked people in a train station.
Protesters wearing black streamed through Yuen Long, even though police refused to grant permission for the march, citing risks of confrontations between demonstrators and local residents.
For the protesters, it was a show of defiance against the white-clad assailants who beat dozens of people last Sunday night, including some demonstrators heading home after the latest mass protest in the summer-long pro-democracy movement. Police said some of the attackers at the train station were connected to triad gangs and others were villagers who live in the area.
The streets of Yuen Long became a sea of umbrellas as the march began Saturday afternoon. A symbol going back to the Occupy Central protests that shook Hong Kong in 2014, umbrellas have become tools to help protesters conceal their identities from police cameras as well as shields against tear gas and pepper spray. Some also wore masks to obscure their faces.
"Hong Kong police know the law and break the law," protesters chanted as they made their way through the streets.

Less than three hours after the start of the march, police fired tear gas to try to disperse the crowd.
The government issued a statement at around the same time warning that police would move in to break up the demonstration.
The statement said that some protesters were "holding iron poles, self-made shields and even removing fences from roads," and that some had surrounded and vandalized a police vehicle with officers inside.
Earlier, the government said in another statement that police were concerned about a "possible deterioration of the situation."
"Police appeal to members of the public to stay calm and leave the area as soon as possible as a chaotic scene may ensue within a short period of time," the earlier statement said.
Hong Kong's public transit network had announced that its trains would not be making their usual stops in Yuen Long on Saturday. Several area businesses and public facilities were closed in anticipation of the march. Service at a nursing center was temporarily suspended, and sports venues shut down early.
A few hours before the march started, a man was arrested in Yuen Long for injuring someone with a knife, police said.
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. The bill was eventually suspended, but protesters' demands have grown to include direct elections, the dissolution of the current legislature and an investigation into alleged police brutality in the Chinese territory.
A former British colony, Hong Kong was returned to China in 1997 under the framework of "one country, two systems." The arrangement promises the city certain democratic freedoms that are not afforded mainland citizens, but some residents say these liberties have been steadily eroded in recent years after the arrests of booksellers and democracy activists.
A distrust of China's Communist Party-led central government in Beijing has undergirded the protests this summer. After last Sunday's march, a group of protesters vandalized Hong Kong's Liaison Office, which represents the mainland government. They spray-painted the building's surveillance cameras and threw eggs and black ink at the Chinese national emblem, an act that Beijing has vehemently condemned.
In response to the police's objection to Saturday's march in Yuen Long, protesters have playfully labeled the procession a "shopping trip," as well as a memorial service for former Chinese premier Li Peng, who died on Monday. Li was a hard-liner best known for announcing martial law during the 1989 Tiananmen Square protests that ended in bloodshed.
Some Yuen Long residents participated in the march, while others stood outside with signs warning protesters not to enter. For their part, demonstrators pasted calls for democracy on sticky notes around the area.
"After the violence (last Sunday), as a resident of Yuen Long, I think I have the responsibility to come out," said a 24-year-old man whose last name is Man. "After all these protests in past months, the government still hasn't responded to us."
