CBC News has learned that a suspicious package found Tuesday at Department of National Defence headquarters in downtown Ottawa contained no explosive material of any kind, and was never a threat to the public.
Ottawa Police said initial X-rays of the package showed what appeared to be wires, batteries and a dense material that could have been components for an improvised explosive device.
But sources close to the investigation say that when police destroyed the package to disable its potentially dangerous contents, they found no explosives or bomb-like devices.
