This is the moment a car, parked without its handbrake engaged, rolled backwards and caused a multi-vehicle pile-up that has left furious motorists demanding compensation.<br /><br />CCTV footage captured on July 13 in Bukittinggi, Indonesia, shows the moment a white 4x4 triggered a chain reaction after rolling down the busy Ahmad Yani street in the West Sumatran city.<br /><br />The accident was reportedly caused when a car crashed into a vehicle that was parked horizontally on the street, causing it to suddenly roll backwards and collide with a row of vehicles that were parked vertically.<br /><br />The vertically-parked cars do not usually engage their handbrakes, but instead, place a small rock behind one of the wheels, locals say. This is done so that vehicles can be easily moved if another car wishes to park.<br /><br />The driver of the vehicle that sparked the chain reaction reportedly fled the scene.<br /><br />Photos and mobile phone footage show the damage caused by the incident, which trashed seven cars, left one motorcycle slightly damaged and also caused damage to a shop-front.<br /><br />Furious motorists now demand that parking officials should offer up to 52m Rupiah (£2,750) in compensation.<br /><br />But the Bukittinggi City Transportation Department says it is unable to offer money for the damages.
