An airplane has crashed in a farm field in southern Indiana, injuring two people.

Lawrence County Sheriff Sam Craig says the single-engine aircraft went down just south of Bedford early Sunday afternoon. Bedford is about 65 miles southwest of Indianapolis.

Craig says his department received a 911 call from 1 of the airplane's passengers about 1 p.m. and emergency medics were dispatched. Both of the airplane's occupants were taken to a hospital for treatment of their injuries, which were not believed to be life-threatening.

The sheriff says the men believed the plane went down due to a "fuel issue."

Craig says the plane had taken off from an airport in Illinois. He released no further details.

Federal aviation officials were expected to begin an investigation late Sunday.
