A second round was found a short time later near a walking path in Galt Gardens.

The Explosive Disposal Unit, with the help of military explosive technicians, was able to safely dispose of both mortar rounds.

Police said last month that they received a report that two suspects were seen in a north Lethbridge neighbourhood in the possession of a backpack that contained what appeared to be two explosive devices.

“The complainant was able to provide a photo of the devices to police, which matched the round located at the SCS,” police said.

They said their investigation to determine who placed the mortar rounds at the SCS and Galt Gardens is ongoing.
