Three pedestrians, including a six-year-old girl and her mother, were injured during a car chase involving police and a suspected drug dealer in Tuen Mun yesterday. The drama began at 12.30pm when officers patrolling in a police vehicle came across a suspected drug deal between a man and a motorist outside Pillar Point refugee camp in Lung Mun Road. As officers approached, the man ran into the camp and the car drove off. Police gave chase in two directions, pursuing the car for 6km. In Shek Pai Tau Road, two packs of heroin were hurled from the vehicle outside an HSBC branch before the car made a U-turn near the junction with Tsun Wan Road. But the driver became stuck in a traffic jam near the junction with Tsing Yeung Circuit. 'The car mounted the pavement, hit railings and knocked down three pedestrians,' said Superintendent Stanley Wong Tat-keung, Tuen Mun divisional commander. 'It then rammed into another set of railings but failed to break through. It reversed, drove off the pavement and sped away.' The pedestrians were Leung Pik-kwan, six, her mother, Cheung Lai-lin, 41, and Lee Wai-fung, 32. They were all treated at Tuen Mun Hospital for minor injuries. Ms Cheung said she had grabbed her daughter and tried to roll on the ground, but they were unable to avoid being hit by the car. They were on their way to Kwun Tong to go shopping. After hitting the pedestrians, the driver negotiated Ming Kum Road and Tsing Wun Road chased by a police motorcycle and police van. The vehicle was finally stopped in Yeung Tsing Road near the junction with Yuk Tsing Lane. The driver fled into Ching Shan Tsuen but officers chased and arrested him. He was held at Castle Peak police station for alleged reckless driving and possession of a dangerous drug. Police conducted a search at the refugee camp and traced the second man. Nothing was found on him.
