A boat malfunction caused a log flume to go backwards down a hill, flipping over and injuring seven people. 

The accident on the Shoot the Rapids ride happened at Cedar Point in Ohio on Friday July 19, the same day a woman died falling out of her seat on a roller coaster at Six Flags in Texas. 

Six of the injured people were treated at the amusement park, while the seventh was taken to a local hospital and was released after being treated.

ABC7news reported Cedar Point spokesman Bryan Edwards said state inspectors were at the park to investigate what went wrong with the park. Edwards said he can't give an estimate of when the investigation of the accident will be complete.

Examiner.com reports that both operators and medical personnel arrived on the scene to help the injured people out of the water, one of whom was allegedly trapped under the boat for several minutes after it flipped. Witnesses said that the accident occurred on the first hill in the water boat ride.  

The report also said the Shoot the Rapids ride at Cedar Point will be closed until park officials determine the exact cause of the boat malfunction that led to the incident.
