A 25-year-old man who developed a gambling addiction after starting work at the Jockey Club and ran up debts of more than $100,000 in less than two years has leaped to his death. Lau Hiu-shan, 25, jumped from a building near his home in Wong Tai Sin with a suicide note in his pocket shortly before 1pm on Tuesday. 'The note said he committed suicide because of financial and family difficulties,' a police spokesman said yesterday. The dead man, a computer programmer, started working part-time as a football gambling operator at the Sha Tin racecourse two years ago. He took the job when his father, a taxi driver, fell ill with cancer and could not work any more. 'He was a very good son until he became addicted to gambling,' his 65-year-old father said yesterday at their fourth-floor public flat in Sau Yuen House, Chuk Yuen South Estate. 'He worked so hard as he knew that our financial situation was not that good,' said the father, who would not give his full name. He said Hui-shan had become addicted to gambling after winning $8,000 with a $50 bet on the football. Since then he had borrowed his father's life's savings of $50,000 and $60,000 from the banks. Just days before Hiu-shan died he had filled out an organ-donor card but even that last wish has gone unfulfilled. Doctors said his organs had been too badly damaged in the fall to be used for transplants. 'I still strive to live, though I am so ill,' wept his father, who has lung and tongue cancer. 'Why didn't he tell me about the problems so that we could try to fix them together?' According to a survey last year by the Christian help group Caritas, one in six problem gamblers has attempted or contemplated suicide due to financial distress. Of 435 pathological gamblers trying to beat their addiction, a further 17 per cent said they had suffered depression.
