LARRABEE, Iowa (AP) — Five workers were injured in the collapse of a building that was under construction in the tiny northwest Iowa community of Larrabee. The Cherokee County Sheriff’s Office says one member of a construction crew was flown to a hospital with serious injuries after the Tuesday building collapse and another was taken by ambulance to a hospital for more minor injuries. Three workers were treated for minor injuries. The sheriff’s office didn’t release names of those hurt. The Sioux City Journal reported that workers were building a frame for a machine shop when the structure collapsed. Larrabee is a city of 120 people, about 50 miles northeast of Sioux City.
