A serial drink-spiker should have been rewarded for the compassion he showed one of his victims, the Appeal Court heard yesterday. Former prison officer Kwok Yuk-ho, 37, took one of the women he drugged to Princess Margaret Hospital, left her in an emergency-room wheelchair and telephoned her parents. 'He obviously had some concern for her well-being,' John Mullick, for Kwok, told the Appeal Court. 'This should have been taken into account.' But the argument made little impression on Mr Justice Benjamin Liu, and Kwok lost his bid to have his 14-year prison sentence reduced. He had admitted blackmail and spiking drinks, and was sentenced last December. Mr Justice Liu said 14 years was 'no doubt severe, but nevertheless a proper sentence for which the applicant cannot complain'. He said drinks manufacturers had suffered because of his crimes. And over the course of his seven-month spree, Kwok stole $391,654, the court heard. From July 19, 1994, to February 20 last year, Kwok injected 10 containers of Vita lemon or chrysanthemum tea with the sleeping drug Rohypnol. He would then shadow his victims after they had bought the doctored drinks from 7-Eleven or Circle-K stores, and when the drug began to take effect he would steal their wallets. Mr Mullick noted that Kwok was a model citizen until he turned to crime. 'He was a Correctional Services Department officer for 15 years before he fell from grace and committed these offences,' he said. On February 20 last year, he took one of his victims to his home and kept her there. He then contacted 25-year-old Lee Lai-see's family and demanded $250,000 for her return. But when they had paid him only $70,000 by February 23, Kwok took her to hospital and called her parents.
