Sources are hard to come by, (Basically the Sandusky Register deleted the story before I could read it.) but it seems as though a chain dog failed on one of the lift hills. The boat then fell down the hill backwards and overturned into the channel of water that guides the ride. Sources say about 10 guests were on the ride at the time.
As of now, no deaths have been reported but we (I) will stay on top of this story as it develops.
Here is the link to the non-existent story about the Cedar Point this. In case it comes back or something.
EDIT:
Ok, so it seems everyone was linking to the wrong page. It did post but not to the above link. Here is the Sandusky Register's story.
