An amusement park ride tilted over at Michigan's Adventure Amusement Park today, leaving more than a dozen injured, according to broadcast reports.
The ride, called The Chaos, tilted over on its side earlier this evening, Grand Rapids television station WOOD reported.
Four patients with minor injuries were taken to Muskegon's Hackley Hospital, and up to 17 were expected, a spokesman said.
Three patients were taken to Mercy General Hospital, said spokeswoman Roberta King. She said they didn't appear to be seriously injured.
Rescue units and helicopters were on the scene, trying to remove people from cars that were stuck in midair.
The Chaos is like a tilt-a-whirl, except its rotating disc tilts up into the air while spinning riders around.
A park official confirmed there was an accident but did not have details. The park is located about 41 miles northwest of Grand Rapids.
