Police fire tear gas at Hong Kongers defying ban on 'anti-triad' rally

Public anger has been raging since last Sunday when a gang set upon anti-government protesters

Hong Kong police fired tear gas Saturday at protesters holding a banned rally against suspected triad gangs who beat up pro-democracy demonstrators near the Chinese border last weekend, tipping the finance hub further into chaos.

Riot police fired dozens of rounds of tear gas in Yuen Long, a town close to the border, after tense standoffs with protesters, some of whom were throwing projectiles and had surrounded a police van.

Public anger has been raging since last Sunday when a gang of men in white t-shirts, armed with poles and batons, set upon anti-government protesters and bystanders in Yuen Long station, leaving at least 45 people needing hospital treatment.

The brazen assault was the latest escalation in seven weeks of unprecedented political violence that shows little sign of abating as the city's pro-Beijing leaders refuse to budge.

Hong Kong has been plunged into its worst crisis in recent history after millions of demonstrators took to the streets - and sporadic violent confrontations erupted between police and pockets of hardcore protesters.

The demonstrations were triggered by a controversial bill which would have allowed extraditions to mainland China, but have evolved into a call for wider democratic reforms and a halt to sliding freedoms.

Police have been heavily criticised for being too slow to respond to Sunday's violence, fueling accusations of collusion or turning a blind eye to the pro-government mob – allegations the force has denied.

In a rare move, police banned Saturday's rally saying they feared reprisal attacks against villagers from protesters.

Social messaging channels used to organise the largely leaderless movement quickly filled up with vows from people to join in.

Some suggested holding a "shopping spree" in Yuen Long, others for a mass gathering of Pokemon Go, a popular mobile phone game.

Large crowds on Saturday afternoon began mustering in Yuen Long's main station and spilling out into surrounding streets where police maintained a large presence but kept their distance. Many shops were shuttered.

Unlike previous rallies, few protesters were holding protest signs or banners. But it was clear those present were determined to defy the ban.

"Everyone of us came here on our own initiation," a 25-year-old medical worker surnamed Ng, said. "So I don't think this is an illegal assembly, I've just come here as an individual to tell people my thoughts."

Another woman, surnamed Cheung, said she wanted to show "we are not afraid and that Hong Kongers won't cower in fear".

Yuen Long is in Hong Kong's New Territories, a rural area where many of the surrounding villages are known for triad connections and their staunch support for the pro-Beijing establishment.

Police say they have arrested 12 people so far in connection with Sunday's violence, nine of whom have known triad links.

Rumours have swirled that protesters might target the ancestral halls and graves of a village close to the Yuen Long's station where the white shirt mob ran into after their attack and later left without police making any arrests despite a large presence of officers.

Earlier this week the graves of Junius Ho's parents were vandalised. An ardent pro-Beijing lawmaker, Ho was seen shaking hands with the white-shirted men before Sunday's attack. He also threatened a pro-democracy lawmaker in an online video earlier this week.
