A butcher who was injured while trying to stop a scuffle in a wet market between his female boss and a rival butcher's wife is suing the latter for $1 million. Lawyer Anthony Cheung told the court yesterday that his client, Cheng Chi-ming, 52, was attacked in September 2000 when he tried to break up the fight. Mr Cheung said Mr Cheng's boss, named Madame Wong, had a fierce rivalry with an adjacent meat store run by the Yau family in a wet market in Tuen Mun. Mr Cheng is suing Li Chau-wan, wife of the rival meat store's owner, and her son, Yau Yick-po, for $1 million in damages for a knee injury he allegedly sustained when he was attacked by the pair. According to Mr Cheung, Mr Cheng's right knee was fractured when Ms Li stepped on his leg. His client had fallen to the ground as he grappled with Mr Yau, Mr Cheung said. Mr Cheung said Mr Cheng was not able to squat, even after recovering from the knee injury. He still experienced pain in his right knee after standing for merely 15 minutes. He also had difficulty climbing stairs. Mr Cheng, who made $700 a day as a butcher, lost his job after taking year-long medical leave. The butcher told the court that on a September day in 2000, he saw Madame Wong and Ms Li scuffling in the store where he worked. Ms Li first pushed Madame Wong against the fridge. She then grabbed Madame Wong's arm and shirt, dragging her to the corridor outside the store. Mr Cheng said he chased the pair in the hope of stopping the fight. He told the pair not to fight as Madame Wong fell on the ground. He stood between the two women, trying to get them apart. He raised his arm to block Ms Li from further attacking his boss. Mr Cheng recalled that all of a sudden Mr Yau came from behind grabbing him around the neck while Ms Li yanked his hair. Mr Cheng said Mr Yau's grip was so tight he could hardly breathe. He tried to break out of the headlock by pinching Mr Yau's right armpit. Both men finally collapsed on the ground as they wrestled with one another. Ms Li then came forward and stepped on his right knee. The hearing continues today in the Court of First Instance.
