Hong Kong motorists driving across the border are falling victim to 'collision gangs' who extort money from them, and a Hong Kong delegate to the Guangdong People's Political Consultative Conference wants provincial authorities to stop the practice. 'The gangs cause accidents that block traffic and many Hong Kong motorists pay so that they can pass by quickly. Otherwise, the accidents are very troublesome for them because it takes time for police to record the particulars of the accident,' said Tse Long. 'The government, especially Shenzhen, should do something to investigate these collision gangs, keep them under surveillance and use the law to resolve the problem.' Mr Tse said 10 Hong Kong representatives to the GPPCC had fallen victim to the gangs. The gangs in Shenzhen prey on vehicles from outside the city and taxis because the owners are more inclined to pay up. They operate with different people playing the roles of victim, mediators and onlookers. They usually stage accidents at zebra crossings or corners where there are more opportunities to stage an accident.
