COURTENAY, B.C. - RCMP say they have evidence to suggest that illegal drug production caused a house to explode in the Vancouver Island community of Courtenay.
Police say equipment used in the production of hash oil was among the items seized on Saturday.
Mounties say one of the three men seriously injured in Friday's blast and fire confirmed their suspicions.
The men in their 20s remain in hospital, and police say no other information will be revealed about their condition to protect their privacy.
Police are reminding people about the risks involved in the production of illegal drugs.
RCMP say the house will need to be assessed to determine if it's structurally safe.
