The younger brother of Occupy volunteer Melody Chan Yuk-fung was punched in the head and private parts by police moments after they arrested him for assaulting a sergeant at last year's Occupy protest in Admiralty, Eastern Court heard. Testifying for himself yesterday, Chan Pak-shan, 24, claimed the beatings took place on two separate occasions; one at a metal fence near where he was arrested and the other inside a police car with lowered curtains. "I was hit in the head, stomach, legs and private parts," he told Deputy Magistrate Winston Leung Wing-chung, of the alleged seven or eight minute attack he endured in the vehicle. He said "hard objects", such as water bottles, were used. Chan, who claimed the overall attack lasted for about 15 to 20 minutes, has denied one count of assaulting sergeant Wong Lok and another of failing to produce proof of identity for inspection. Yesterday, he also told the court that a police officer allegedly declared they were from Wo Shing Wo, a notorious triad group in Hong Kong, while in the police car. The court was told on Monday the alleged attack happened on September 29, the second day after tear gas was fired near the Central Government Office. On the night, Chan was having a "loud" discussion with his friends as they strolled along Lung Wo Road about why police were leaving the engines running on their idle cars. Chan claimed an officer in a white shirt suddenly appeared and summoned about 20 other officers to gang up on him. Wong had earlier alleged that Chan punched him in the chest after he asked Chan for identification. Both accused the other of using foul words. While the court previously heard Chan suffered bruises around his left eye and on his nose and chest, Wong had bruises on his chest. In cross-examination, prosecutor Priscilia Lam Tsz-ying questioned why Chan had not told the doctor about the attack on his testicles. She also suggested Chan had not told the officer on duty at the police station he was taken to of the beating at the metal fence nor the triad-related claims. She accused Chan of giving a version of events different from the one his lawyer told the court. Chan disagreed with Lam's suggestions and claimed that police used "eye contact" to threaten the doctor when he asked about taking photos of the injury around Chan's private parts. Magistrate Leung adjourned the court until May 19 for verdict.
