A Greyhound bus flipped over and landed on its side in an Ohio cornfield early on Saturday, injuring more than 30 people, some seriously, authorities said.
The bus was traveling on Interstate 75, when the crash occurred at 3:48 a.m. in Liberty Township, about 25 miles north of Cincinnati, said Jeff Galloway, director of the Butler County, Ohio Emergency Management Agency.
There were 51 passengers plus the driver on board the bus, which was en route from Cincinnati to Detroit, Michigan.
Of the injured, 28 were put into ambulances and six airlifted to hospitals, Galloway said.
"The injuries range from serious to minor," he said.
The Ohio State Highway Patrol was investigating the cause of the incident.
Galloway said there were no signs that the bus was speeding.
"No indication of anything," he said. "That's all under investigation."
