Police investigating how burning truck snapped power after hitting Stobie pole on Cemetery Rd at Callington SEVERAL homes in the Adelaide Hills were left without power last night after a burning truck brought down power lines. The burning Ford Courier delivery truck, on Cemetery Rd at Callington, was reported to CFS crews about 10.30pm after residents heard a loud popping sound. A CFS spokeswoman said the burning truck had rolled down the street, hitting a Stobie pole and dislodging a low voltage power cable. The fire was quickly extinguished but the truck was completely gutted. An SA Power networks spokeswoman said about 20 homes were affected by the power outage, but most power was restored by 12.30am. Two homes were left without power until 3am. Police said they are investigating "who started the blaze." No one was in the truck when it was found and no one was injured. Anyone with information about the fire should contact Crime Stoppers on 1800 333 000 or www.sa.crimestoppers.com.au
