A 25-year-old Edmonton man is facing multiple firearm-related charges after officers discovered a cache of ammunition and artillery in a converted bus. 

Police say they converged on the bus in west Edmonton earlier this week after complaints that someone living in the bus was threatening people. 

Officers found numerous loaded handguns and military-grade arms, including M-14 and Chinese SKS rifles and over-capacity magazines in the bus.

The man has been charged with careless storage and possession of restricted and prohibited weapons.
