The theft from the Westview Coop Cardlock took place between 3 and 3:30 a.m. Closed-circuit camera footage shows the truck pulling up and taking the fuel, RCMP said. The volume taken was not specified in the release.
The suspect vehicle is described as a triple-axle tanker truck with a two-tone red and white semi chassis — red hood and doors with white fenders — and a white tank.
Olds RCMP is asking anyone who was in the area at the time and may have dash-cam footage of the truck to contact them. Anyone who spots a fuel truck matching that description is also asked to contact their local police.
RCMP said the theft is part of a pattern of high-volume diesel fuel thefts and is recommending that fuel stations install anti-siphoning devices in ground-based tanks to help prevent further incidents.
Anyone with information can contact Olds RCMP or reach Alberta RCMP Media Relations at 780-509-3970.
