MASON, Ohio - Some roller coaster fans at Kings Island got a big scare while riding The Beast on Tuesday.
The coaster became stuck at about 11 a.m. on the second lift hill, park officials said.
Spokesman Don Helbig said the riders were stuck for about 10 minutes before being escorted off the ride. Thirty people were on the ride at the time.
Apparently a malfunction with a computer-operated safety system caused the train of passengers to become stopped.
Helbig said the system is designed to pace all of the cars to make sure that the coaster cars don't get too close to each other and crash. He said this used to have to be done manually by an operator but is now computer-assisted.
When the system shut down, it caused the train cars to stop. While they were waiting, one rider had an anxiety attack and called 911 for help from the ride.
Helbig said no one was injured and the ride was reopened at about 12:30 p.m.
