The mini backpack contained about 30 grams of crystal meth.
Speaking to Global News, John Randle, president of the Pacific Region for Union of Canadian Correctional, said, "A pigeon was located at Pacific Institution, inside the walls and it appeared to have a small package, sort of like a backpack attached to it."
The officers had to corner the bird in order to catch it.
It's definitely scary with the fact that it was crystal meth that was found on the bird because that causes a whole lot of problems," he added, as per the outlet.
For now, they have increased staff and patrols in order to watch for any potential drops.
