The husband of a cashier killed in the Top One Karaoke firebombing is suing the bar for nearly $740,000. Seafood chef Ip Lui-tat, 27, is seeking employee's compensation because he and his four-year-old son were both wholly dependent on his wife Lam Pui-yi at the time of her death, lawyer William Lee Wai-sang said. Lam, 27, died of smoke inhalation after the Tsim Sha Tsui karaoke bar was set ablaze on January 25 last year following a fight between rival triad gangs and bouncers, District Court Judge Judianna Barnes Wai-ling heard. Mr Ip testified that 10 days before his wife's death he had quit his job as a cook in Zhuhai to spend more time with his family. He and his son were dependent on his wife's salary of $8,799 a month. Under questioning by Top One's lawyer, Patrick Burke, Mr Ip admitted that while he was working in Zhuhai his monthly contribution to the household had been $12,000 from a salary of $15,000. But he denied he bore all responsibility for the family. 'If I was the sole person responsible I would not require [my wife] to work in a karaoke bar,' he said. His wife had worked as a cashier in Top One since December 1995, but had planned to quit because there had been several fights. The Prat Avenue bar was firebombed by members of the Sun Yee On five days after a fight broke out between gangs and bouncers. Seventeen people died. Mr Burke conceded that Top One was liable for compensation, but disputed the $739,116 figure. The hearing continues today.
