A teenager was so traumatised by watching her father die in hospital that she has since become a paranoid schizophrenic, says a writ. Cheung Kwai, the mother of Jiu Kit-choi, 18, is suing the employers of her late husband, Jiu Kwai-shing, for unspecified damages in the High Court. Lawyers claim the employer had a duty to the teenager not to expose her to the risk of nervous shock or psychiatric injury. Kit-choi was a healthy girl until learning that her father had fallen from scaffolding on October 25, 1996, the writ says. She was alone at home when police telephoned to inform her of Jiu's accident in Texaco Road, Tsuen Wan. Kit-choi waited for Ms Cheung to go home before going to Yan Chai Hospital. She was 'further distressed by the sight of the deceased who had . . . a head injury and was comatose'. Jiu was transferred to Queen Elizabeth Hospital at about 7.15pm. Kit-choi followed in a taxi and when she arrived at 8.17pm saw 'blood oozing from the mouth of the deceased'. Doctors concluded the following March that she was suffering from paranoid schizophrenia. Named as defendants are Tang Hon-chiu, trading as Lee Hong Scaffolding Works, and the personal representative of the estate of Lui Joi-kong. Lui, who used to trade as Shui Hing Construction Co, has since died.
