Two thieves escape after fourth highway raid in three months An armed gang hijacked a van carrying $3.7 million worth of electrical goods and dragged the driver and a co-worker out onto a Kowloon Bay overpass yesterday. It was the fourth highway robbery in three months. The daring daylight raid happened just before 1.30pm when van driver Man Chiu-hung, 39, was transporting 43 boxes of electrical goods from Tsuen Wan to Kowloon Bay. A blue car travelling in front of him stopped suddenly, forcing his van to a halt on the Kai Cheung Road overpass. A goods vehicle behind them failed to stop in time and rammed into the van. No one was hurt in the collision. Motorists were stunned to see two bandits - one armed with a pistol or replica and the other with a knife - jump out of the car. One driver reported the hijack. 'The two robbers wearing sunglasses and caps threatened the driver and his co-worker with what appeared to be a pistol. The two victims were then pulled out of their vehicle,' a police spokesman said. One robber jumped into the goods van and drove off while the other escaped in the car. Heavily armed police officers wearing bullet-proof vests set up road blocks and mounted a huge search. The hijacked van was found torched an hour later in Ede Road, near the junction with Beacon Hill Road, in Kowloon Tong. No arrests had been made by last night, nor had the blue car been found. The driver of the goods van and his co-worker, Li Shue-wing, 18, were not injured in the incident. The spokesman said officers were investigating whether the raid was linked with previous highway robberies. Kowloon East regional crime unit detectives are investigating. It is understood that officers were also looking into the possibility the robbery was an inside job. On August 3, three bandits escaped with $3.5 million worth of semi-finished mobile phones after hijacking a station wagon in Sha Tin. The driver was held at gunpoint and bundled into a white goods van before being tied up and blindfolded. He was then pushed out of the vehicle in Chai Wan. On July 1, three robbers hijacked a truck in Tsuen Wan carrying LCD monitors worth $7.8 million after pistol-whipping the driver, who was put into a sack and dumped at Chuen Lung, north of Tsuen Wan, on Route Twisk. On June 17, a truck loaded with $7 million worth of silver bars, weighing about five tonnes, was hijacked on the Ting Kau Bridge near Tsing Yi. Six robbers fled with $1 million worth of silver after police spotted them unloading the metal in a Kowloon City car park. Police officers last month arrested four men in connection with the crime.
