A tornado that ripped the roof off a sports arena in Billings, in the US State of Montana, on Sunday evening also tore through businesses, damaged a bar and a casino and left just the walls of an auto glass shop standing.
The tornado struck at about 4:30pm (2230 GMT) as a big storm system with golf ball-sized hail passed through the area, the US National Weather Service said.
After running through Main Street in the city's northeast area, the twister quickly moved toward the 10,000-seat Rimrock Auto Arena about a half-mile away, where it hovered for about 15 minutes, snapping trees and telephone poles.
The tornado was caught on tape with the pictures showing large amounts of debris flying through the air.
Big pieces of metal were left hanging from power lines near the arena, and tangles of insulation and metal debris were strewn for hundreds of yards in the surrounding industrial area.
There were several employees inside the arena when it struck, but there were no reports of injuries, police said, adding that there had been no reported deaths and no-one reported missing.
In fact, the only injury was said to be someone who was hit on the head by a hail stone.
City officials were working to clean up the mess and were dealing with power outages and flooding from the storm, which sent about two feet of water into many city streets.
Wind speeds from the tornado were estimated to range between 111 and 135 mph.
