GREAT FALLS, Mont. — Federal investigators have recovered a large portion of the more than $21,000 in professional fireworks and equipment stolen a day before the City of Great Falls’ planned July 4 fireworks display.

Great Falls Police credit Bureau of Alcohol, Tobacco, Firearms and Explosives agents with recovering the explosives.

The fireworks were stolen from a cargo trailer owned by Big Sky Fireworks. They were replaced in time for the city-wide display.

Sgt. Jim Wells says some of the fireworks are still missing and are dangerous. He described them as looking like a cannonball wrapped in cardboard with what appears to be a fuse, but is not one. He said attempting to light one could lead to serious injury or death.

Officials did not say where the fireworks were recovered or if any arrests have been made.
