Two policemen drew their guns to stop a car when its driver tried to ram them after a four-kilometre car chase yesterday. The 33-year-old driver of the two-door Lexus was arrested for dangerous driving, driving with his licence disqualified and without third-party insurance and driving an unlicensed vehicle. The chase began on the Tsing Sha Highway in Tai Wai at 12.15pm, when a new automatic number plate recognition camera on an unmarked police car scanned the car's number plate and found its licence had expired. Police officers sounded a siren and ordered the vehicle's driver to pull over, but he ignored their command and sped off, the police said. Four traffic officers gave chase in a police car. The white Lexus led them at high speed into the Fo Tan industrial area. A senior police officer said the car had been clocked travelling at more than 100km/h in 70km/h speed zones during the pursuit. "In an effort to evade police in the industrial area, the car kept switching lanes, crossed double white lines and travelled on the wrong side of the road on several streets," he said. "A number of vehicles had to brake heavily to avoid colliding with the car." The 10-minute chase ended when the Lexus entered a cul-de-sac. The police blocked the road with their car, but the driver kept looking for an escape. When police approached the car, the driver accelerated in an apparent attempt to hit two traffic policemen, according to Chief Inspector Tam Kan-lun of Sha Tin police station. The two officers - a Western inspector and a local constable - were just a metre away from the car at the time. "To protect their own safety, the two colleagues drew their guns and aimed at the car," Tam said. "It immediately stopped." Police then arrested the driver. His girlfriend, 24, was also in the vehicle. No one was injured. Tam said there was no evidence the man was driving under the influence of illegal drugs. He also passed a breathalyser test. Officers found four number plates in the car. One of them did not belong to either of the pair. Police also arrested them on suspicion of preparing for a robbery. The driver was released on bail and must report to police later this month.
