Police are investigating a YouTube video clip that apparently shows a Hong Kong minibus driving onto a footpath to get past a traffic jam at a congested Mong Kok junction. The clip, which runs for one minute and 25 seconds, shows a red-topped minibus cutting from the right lane of Sai Yee Street into the left lane before joining a queue of vehicles waiting at a traffic light at the junction with Argyle Street. About 15 seconds later, the passenger-laden minibus tries to drive to its left onto the footpath in front of the Water Supplies Department office. But a motorcyclist beats the minibus and squeezes through the space, followed seconds later by the minibus. Both vehicles travel along the footpath, which is apparently empty, passing about three vehicles before moving back onto the road. The clip, taken from a vehicle behind the minibus at about 7.40pm on Thursday, shows a woman pedestrian slowing her pace to give way to the minibus mounting the footpath a few metres in front of her. Cable TV traced the male driver of the Route 71 minibus, which runs between Mong Kok and Hung Hom, identifying him only as Mr Tse. In a telephone interview with a presenter, Mr Tse said it was unusual for him to run onto the pavement. He refused to comment further, saying he was too busy to talk. Cable TV also found the motorcycle's owner, a Mr Lau, who said his vehicle had been borrowed by a friend but the friend could not remember the incident. Another minibus driver on the same route told Cable TV it was not unusual for drivers upset by traffic jams to drive onto the footpath. A police spokeswoman said the Kowloon West traffic investigation unit was looking into the case. Police would act if anyone had broken traffic laws. She urged anyone with information about the incident to call police on 2773 5200. She said the drivers involved might have committed offences that could result in jail terms of up to three years. A Transport Department spokeswoman said the department would send letters to the owner of the minibus concerned and leaders of the trade to remind them about observing traffic regulations.
