The theft of 250 kilograms of explosives from a Whitehorse business over the weekend is under investigation, RCMP say.

Cpl. Grant MacDonald said RCMP learned Tuesday afternoonof a break-and-enter at Yukon Pump, a mining and construction supply business in Whitehorse.

Upon arriving at the scene, officers discovered that thieves broke into the building over the weekend and stole 10 boxes of an explosive blasting agent weighing a total of 250 kilograms. The business operators did not notice the materials were missing until Tuesday morning.

The stolen boxes contained two cartridges each of a "putty-like substance" in white plastic tube-wraps with the word Tovite written in red on each cartridge. Each tube-shaped cartridgeis about 13 centimetres in diameter and 90 centimetres long.

"There is no danger to the public in relation to this blasting agent that has been taken in of itself," MacDonald said Wednesday.

"My understanding is that in order to cause an explosion … there would need to be something else used, like a blasting cap."

At the same time, MacDonald said anyone who may spot the stolen explosives should not go near them, instead taking note oftheir location and contacting police immediately.

The RCMP have asked anyone who has seen the stolen explosives or witnessed any suspicious activity at the Yukon Pump building to call the Whitehorse detachment at (867) 667-5555 or Crime Stoppers at 1-800-222-TIPS (8477).
