State inspectors are at a popular Ohio amusement park to figure out how a boat on a thrill ride accidentally rolled backward down a hill and flipped over in water, injuring seven people.
Cedar Point spokesman Bryan Edwards says the inspectors and officials at the Sandusky park are investigating what went wrong with the Shoot the Rapids water ride Friday.
Six of the injured passengers were treated at the scene. The seventh was taken to a nearby hospital and was treated and release.
The ride remains closed, but the park reopened Saturday.
Edwards says he can't give an estimate of when the accident investigation will be completed.
He says Cedar Point's top priority is the safety of the park's visitors.
