A group of concerned residents has condemned the police action against Occupy protesters in Admiralty earlier this week and urged the Independent Police Complaints Council (IPCC) to launch a probe. They also called on Police Commissioner Andy Tsang Wai-hung to apologise. "It was like [the police] were acting in a red haze of violence," said Dr Au Yiu-kai, who is a veteran international relief doctor and the volunteer head of medical services for the "umbrella movement". "In Mong Kok, injuries happened on the front line. I don't condone violence, but the situation was understandable. What happened on Lung Wo Road was different - police continued to beat up retreating people," said Au. "This was completely outrageous." Au and a group of parents, clergy and academics joined forces in condemning what they called the excessive and unnecessary use of force by the police during clearance operations in Admiralty and Mong Kok. The group collected over 5,000 signatures for a letter to the police, demanding that the IPCC thoroughly investigate the use of violence in the two places and for the report to be released to the public. They also called on the police chief to apologise. Au said he was chased from Lung Wo Road to Tamar Park while trying to staunch a protester's bleeding head on Monday morning. He said he had started to bandage the wound when a group of officers came at them. One hit the protester's injured head with a baton, he said. "I shouted that I was a doctor and they could see I was doing medical work. Another police officer yelled: 'I don't care if you're saving lives, I will still arrest you'. Luckily other protesters were around and dragged me away," Au said. At least 16 medical personnel and 33 emergency volunteers were injured, including one who was beaten over the head with a baton, he said. The IPCC said yesterday that it would not send observers to inspect Occupy protest zones. "It will be the individual choice of committee members if they want to make on-site observations," said IPCC secretary general Ricky Chu Man-kin. "As far as the IPCC as a statutory body is concerned, we need to maintain our impartiality," he said. More than 1,700 complaints related to the Occupy movement have been filed against the police since protests started in late September. Meanwhile, Alliance for Peace and Democracy spokesman Robert Chow Yung said police had exercised necessary but not excessive force to stop protesters. "They have done a great job to protect Hong Kong and the Hong Kong public," he said yesterday, during a rally to express thanks to the force outside police headquarters in Wan Chai.
