Four people sustained minor injuries in an explosion at a Garden City, Idaho, business Wednesday morning.
The explosion happened just before 11 a.m. in Garden City, officials said. The explosion at Henderson Wheel and Supply was caused by a simulator round used in an M21 military tank, Garden City Police Sgt. Tyler Domeny said.
The round, which Domeny said is similar to a blank round of ammunition and used for sound purposes, was found outside of the store and brought in by an employee. Employees mishandled the round and took its cap off, which caused the explosion, Domeny said.
“This is something that’s used in a military tank,” Domeny said. “It had no reason being there.”
Domeny said there were “no indicators that there’s any future issues here,” but Boise Police Department’s Explosive Ordnance Disposal and hazmat teams continued to sweep the area into the afternoon.
