FORT SIMPSON, N.W.T. (CP) - A curious black bear caused an oil spill near this town in the Northwest Territories, say officials.

About 12,000 litres of oil, equal to about a dozen household tanks, leaked out after the animal accidentally opened a valve at an Enbridge Pipelines site.

Nick Larter, a biologist for the Department of Resources, Wildlife and Economic Development in the Deh Cho, said bears are naturally curious and especially like to play with anything soft and rubbery.
