Six Flags says a water ride in suburban St. Louis has been shut down after a rider fell out of a tube and was taken to a hospital as a precaution.

The St. Louis Post-Dispatch reports that the accident happened Saturday on the Typhoon Twister. The ride, which opened this summer in Eureka, sends a four-person raft careening into a 125-foot-long whirlpool bowl, down a five-story drop, up a 45-foot zero-gravity wave wall and back down into a splash pool

Spokeswoman Elizabeth Gotway released no information about whether the rider had injuries or how long the ride will be closed. Six Flags didn't immediately return phone or email messages Tuesday from The Associated Press.

The park said in a brief statement that it's looking "into the circumstances" of what happened.
