A 31-year-old bus mechanic who filed bogus reports of road accidents has been remanded in custody until July 27 after admitting in Kwun Tong Court yesterday he was responsible for the pranks. Acting Principal Magistrate Amanda Woodcock refused to consider immediately fining Chan Ka-wai, who was accused of wasting police time, saying that he had committed serious offences. The court heard that Chan made four calls within two weeks while working at the KMB depot. He was caught after police traced his mobile phone. Chan, who admitted the offences, called the police hotline on April 13, 27 and twice on April 28, to report accidents in different part of the city, wasting 61/2 hours of police time at a cost of HK$730.60. In the first two calls Chan reported a taxi on fire in Nathan Road and a cyclist trapped under a taxi near the Mong Kok MTR station. In one, he claimed two cyclists had fallen into a reservoir in Shek Lei Pui, and in another he said a truck was on fire outside an MTR exit at Sham Shui Po with three people trapped inside. On the last occasion, police called his mobile number after they found no accident. Chan answered the call and directed the police to two other exits. Police later traced his number and in May arrested Chan, who said that he had made the bogus calls 'out of impishness'.
