Dallas County first responders were called to an accident involving a dump truck on 360th Street just south of De Soto early Saturday afternoon.

De Soto Fire and Rescue Chief Tim Murray tells Raccoon Valley Radio two men were servicing the back end of a dump truck when the truck inadvertently tipped over and fell on top of one of the workers.

The person was taken to Iowa Methodist Medical Center in Des Moines via Lifeflight helicopter. His condition is unknown at this time.
