Universal Studios told Local 6 Escape from Gringotts was evacuated Saturday morning after a technical glitch forced the ride to shut down.
A Local 6 viewer said the ride was completely full when the ride stopped and the lights came on.
The viewer said they were stuck on the ride for at least 40 minutes while workers tried to make repairs.
Universal Studios said all guests were safely evacuated and there were no injuries.
Officials said the ride was repaired and operational a short time later.
