Two black bear cubs have been captured after their mother was killed in Whitehorse Tuesday morning.

Yukon conservation officers captured the cubs Tuesday afternoon after their mother was killed by officers in the Copper Ridge neighbourhood.

After the mother bear was destroyed, officers began a search for her cubs.

"They are safe in our possession right now," said Ryan Hennings, a conservation officer with Environment Yukon.

"They will be examined by staff to determine their health and we are going to temporarily hold them at the wildlife preserve while we look for a facility to take them."

The bears had been relocated across the Yukon River two weeks ago after breaking into garbage bins but they swam back and returned to the residential neighbourhood.
