THREE men kidnapped a man who refused to pay a debt, holding him for 24 hours in a shack in Tai Po before they were caught trying to collect the ransom, the High Court heard yesterday. Choi Kwok-king, 25, Cheung Kim-por, 24, and Tse Tim-cheong, 26, all pleaded guilty to kidnapping Mr Wilson Ng Din-on, who owed Mr Dickson So Cheng-fat $28,000. Mr So asked Choi to collect the debt, promising one half of what he recovered. Choi recruited his co-accused. Deputy Judge Evans heard that the three men visited Mr Ng at his home, his work place and a restaurant but failed to get the money from him. Police were called in but they only encouraged Mr Ng to pay his debt. At about 11.30 pm on March 11, 1992, the three defendants drove to Mr Ng's home. As he walked by, they bundled him into their van and took him to a shack in Tai Po. Mr Ng was kept overnight and his family was telephoned and asked for payment of the debt. Choi was arrested by police when he went to meet Mr Ng's wife to collect the ransom. Cheung and Tse later gave themselves up. Passing sentence, the judge said Mr Ng was not hurt during the detention. Sentencing Choi to two years' jail, the judge said he was the prime mover in the offence, but he got a larger discount for offering to give evidence against the other two, after which they too had pleaded guilty. Cheung was also sentenced to two years' and Tse, who was not present when demands for money were made, to 18 months. Earlier, defence counsel said Mr Ng had set out to defraud and so had to some extent brought this on himself.
