HONG KONG — Hong Kong's police force said Wednesday it will investigate after officers were caught on camera kicking a handcuffed protester amid the most violent clashes since street demonstrations for greater democracy began more than two weeks ago.
Hundreds of riot police, some wielding batons, pepper spray and shields, knocked activists to the ground and dragged dozens away as they moved in to clear them from an underpass next to the government's headquarters early Wednesday.
The clashes sparked public outrage and worsened an already bitter standoff between authorities and activists, who have taken over the city's key roads and streets to press demands for democratic reforms.
Anger over the aggressive police tactics exploded after local TV showed a group of plainclothes officers taking the protester around a dark corner and kicking him repeatedly on the ground. It was unclear what provoked the attack. Local Now TV showed him splashing water on officers beforehand.
The protester, Ken Tsang, said officers assaulted him while he was "detained and defenseless," and that he was attacked again in the police station afterward. Tsang, a member of a pro-democracy political party, lifted his shirt to show reporters injuries to his torso and said he is considering legal action against police.
Police spokesman Steve Hui said seven officers who were involved have been temporarily reassigned, and that authorities will carry out an impartial investigation. Police arrested 45 demonstrators during the clashes, and said five officers were injured.
"Hong Kong police have gone insane today, carrying out their own punishment in private," said pro-democracy lawmaker Lee Cheuk-yan. "Hong Kong's values and its rule of law really have been completely destroyed by police chiefs."
Beijing, meanwhile, issued its harshest condemnations yet of the protests, calling them illegal, bad for business and against Hong Kong's best interests. The central government has become increasingly impatient with the demonstrations, the biggest challenge its authority since China took control of the former British colony in 1997.
A front-page editorial Wednesday in the People's Daily, the ruling Communist Party's mouthpiece, condemned the protests and said "they are doomed to fail."
"Facts and history tell us that radical and illegal acts that got their way only result in more severe illegal activities, exacerbating disorder and turmoil," the commentary said. "Stability is bliss, and turmoil brings havoc."
However, there were no signs that the central government was planning to become directly involved in suppressing the demonstrations, which have marshalled opposition to plans for a pro-Beijing committee to screen candidates in Hong Kong's first election to choose the city's chief executive in 2017. The protesters also want the current leader, deeply unpopular Leung Chun-ying, to resign.
The demonstrations have posed an unprecedented challenge to the government, and it is unclear when and how the crisis will be resolved.
Leung, who described the protests as being "out of control," told reporters that officials are willing to talk to protesters, but reiterated that Beijing will not drop the election restrictions it imposed. He canceled a leader's questions session at the Legislative Council on Thursday, citing security risks.
The police operation early Wednesday came hours after a large group of protesters blockaded the underpass, expanding their protest zone in apparent retaliation after police closed in on the occupied areas and cleared activists out of a key thoroughfare.
Police said they had to disperse the protesters because they were disrupting public order and gathering illegally. They also said protesters acted aggressively toward officers.
After initial attempts to disperse protesters with tear gas and pepper spray backfired two weeks ago, police have adopted a strategy of gradually chipping away at the three protest zones by removing barricades from the edges of the occupied areas in the early morning, when the crowd numbers are usually lowest.
But Wednesday's raid was the most violent so far, with police charging the protesters and dragging them away. One officer ripped a facemask off an activist before spraying him with pepper spray, according to a video on the South China Morning Post newspaper's website.
"Some of us were sleeping in the park when more than a hundred of them ran toward us with torches as if they're trying to blind us temporarily. We were not prepared for how aggressive they were," said protester Simon Lam, 22.
Positions on both sides have been hardening since the government called off negotiations last week, citing the unlikelihood of a constructive outcome given their sharp differences.
Beijing is eager to end the protests to avoid emboldening activists and others on the mainland seen as a threat to the Communist Party's monopoly on power.
In language freighted with political symbolism, Zhang Xiaoming, director of the central government's liaison office in Hong Kong, was quoted as telling Hong Kong legislators at a banquet Tuesday that the protest movement "is a serious social and political incident."
Zhang said the movement challenged Beijing's authority and had caused the city to suffer huge economic losses. It had "hurt the basis of Hong Kong's rule of law, democratic development, social harmony, international image and its relations with the mainland," he said.
Zhang called for an end to the protests as soon as possible to avoid further losses to Hong Kong's citizenry.
But Lam, the student protester, said he was bracing for more tensions as students' distrust of police grows.
"Now there is a feeling we are not just here to fool around or just to sit peacefully. We are feeling more prepared. We have become more united in building defenses," Lam said.
