Local authorities and the Health and Safety Executive (HSE) have begun enquiries into how a lighting panel fell from a twister-style ride while it was in motion.
No one was injured during the incident at Paignton seafront on Tuesday night, and the ride has remained closed since.
The Devon Live website reported that a “six-foot-long lighting panel crashed to the ground, smashing its bulbs”.
Two people were understood to be riding as one of the last rides of the evening.
Fairground operator Simon DeVey of Anderton and Rowland said that the ride will stay closed until his staff had “gone through all the procedures”.
“Luckily no-one was hurt,” he said. “We’re not sure what happened, and we are not using the ride until it has been inspected and we have found out why it happened.
“It’s a top-notch ride, and it has just been refurbished at a cost of £20,000, so we can’t understand it. But when these things happen, we’ve got to take every measure possible.”
The HSE was quoted as saying: “HSE has been made aware of an incident at the Anderton and Rowland fairground and is making initial enquiries.
“Torbay Council has confirmed there are no reported injuries and is also making enquiries as the fair is on its land,” it added.
