Two secondary school students were among four males who seized and badly beat an alleged drug runner over an undelivered consignment, the District Court heard yesterday. Unemployed Tse Yiu-ming, 28, teenagers Lam Leung-tat and Pak Chun-man, both 18, and a 15-year-old boy have been accused of false imprisonment and the wounding of Lai Kai-pong, alleged runner for a man known only as 'Fei Gau'. Tse pleaded guilty to false imprisonment, theft and wounding, while the other three pleaded not guilty. Lam was a Form Five student when the offences were allegedly committed in April last year, while the 15-year-old, who cannot be named because of his age, was a Form Two student. The prosecution alleged, and Tse admitted, that Mr Lai was given $5,200 in March last year to buy 14 grams of cocaine from a drug supplier. He purchased the cocaine but did not give it to Fei Gau, instead selling it to someone else and pocketing the money in lieu of unpaid salaries from Fei Gau in the past. On April 21, Mr Lai bumped into Tse and Fei Gau in a Mongkok restaurant. He was taken to a flat in Tong Mei Road and beaten by Fei Gau. Tse, known as 'Tai Ngan', meaning 'big eyes', was present throughout. Tse and Fei Gau then took Mr Lai to two discos 'for entertainment', after which he was taken to a Shamshuipo flat and kicked and punched by Fei Gau. Tse also punched him, demanding repayment. Mr Lai was coerced into handing over his ATM card and password, and $500 was withdrawn from his account by another man. Tse was again present. Fei Gau continued to beat Mr Lai, hitting his knees and back with a hammer and hitting him on the head with a metal pipe. When Mr Lai's bleeding would not stop, Fei Gau - who remains at large - asked another unknown man to apply stitches and injections. Then, in the early hours of April 22, Fei Gau and Tse took Mr Lai to the Cyber nightclub in Tsim Sha Tsui to parade him around, and afterwards took him to another Shamshuipo flat, where Tse locked him in on the instructions of Fei Gau. Fei Gau returned in the afternoon intending to beat up Mr Lai but was stopped by Tse, who was in the flat with five other youngsters, including the three other defendants, watching Mr Lai. At one point, the observers all fell asleep and Mr Lai called the police using Tse's mobile phone. The case continues today.
