Men between the ages of 24 and 54 will be charged at a press conference on Monday for "unlawful gatherings" of police. Their motives are still under investigation, but the police said that some of the detainees had ties to local criminal gangs known as triads.
Footage published on social media showed a marauding band of masked men wearing white T-shirts and batons carrying sticks blindly attacking the crowd on the platform and in the carriages of Yuen Long MTR station in the extreme northwest of the city ,
Many of those affected returned home after participating in mass demonstrations in the city, leading to the allegation that the gangs had been paid to stir up riots and attack demonstrators.
Forty-five people were hospitalized with a person in critical condition after the Yuen Long violence, Hong Kong Information Services said. Videos showed people being beaten and left bloody and dizzy on the ground.
The incident angered many in the city. The police took about an hour to get there and did not make any arrests that night. The nature and speed of the attack also makes people question the ability of the Hong Kong police to protect the city's residents.
Protesters vowed to march in Yuen Long on Sunday to protest the violence.
What or who are Triads?
The six men were arrested after raids Englisch: www.germnews.com/archive/eng/news_2006.html The suspects were on Monday in Yuen Long and in the nearby districts Tin Shui Wai, which are near the Chinese border, including drivers, salesmen, renovation workers and the police have been unemployed and police said some had a "triad background".
Triade is a name for Hong Kong's organized crime syndicates that earn their money through illegal drugs, gambling, and prostitution, among other things. It has also become a reference to loose organized criminal gangs in the city. Some groups, especially the larger, more powerful gangs working in rural New Territories villages, exercise political power over district councils and other political connections.
Police Commissioner Stephen Lo denied on Monday the allegations that police officers were working with gangs hired to attack protesters, saying the delay was due to police resources being located on the main protest site on Hong Kong Island, about an hour from Yuen Long away, were used.
"We will investigate if we were inefficient But we are not related to triads I ask you to trust the police Last night we all concentrated on the island of Hong Kong We had to regroup ourselves for Yuen Long" , he said.
Hong Kong chief executive Carrie Lam called such allegations "insulting".
Similar allegations were made in 2014, when masked men with alleged links to organized crime were demonstrators of the Umbrella Movement w He had occupied Mong Kok district for weeks. Protesters said the police did not protect them and did not arrest people who committed violence, a charge the troupe then denied.
Researchers Federico Laut Varese of the University of Oxford and Rebecca WY of Wong City University in Hong Kong have "possibly found a new role for Triad groups as executors of unpopular politics and the suppression of democratic protests in the context of a tendency towards authoritarianism in Hong Kong" ,
Professor T Wing Lo, an expert on triad societies at City University in Hong Kong, told CNN that the degree of organization in Sunday's scenes suggests that he was led by a triad group.
"But the participants were not all Triad members," he said. "Some were just ordinary villagers, others were paid for their work."
Lo said the group that carried out the attack in Yuen Long would probably have been paid by pro-Chinese authorities.
"All of Triads committed crime is against money, "said Lo. "We call that extra-legal governance – sometimes, when governments can not use formal law enforcement for whatever reason, they pay for it, which is the normal way to do business."
While the police have not confirmed the incident in Yuen Long, coordinated under the leadership of a Triad group, the phenomenon of criminal grafting in mainland China is spread across borders.
" Third-party violence is commonly used by the state to evict homeowners and deal with petitioners and protesters in China, "Ong said in her 2015 paper.
This alleged connection between the Hong Kong and Hong Kong traid groups The Chinese authorities on the mainland date back decades.
After the 1989 Tiananmen Square massacre and several triad groups fighting for the smuggling of escaping democratic leaders, Beijing pursued a "focused strategy" to "end the triad in the Beijing Pro-camp to lure "Exchange for Support in Hong Kong."
"Before the island was surrendered to China in 1997, the Beijing government feared that the Triad societies, particularly the most powerful Sun Yee On Triad, would be dealing with Liberal "Put together political activists and destabilize the post office" -1997 Hong Kong, "said Varese and Wong.
