A ride at The Mart had to be closed for four hours after a small piece of plastic fell off.
The Altitude ride was halted on Wednesday afternoon after the plastic fell from the ride and landed on a nearby arcade roof in Lynn’s Tuesday Market Place.
West Norfolk Council has praised the operator for the swift repairs but has notified the Health and Safety Executive (HSE) of this incident.
A council spokesman said the plastic came loose about 2pm and the ride was immediately taken out of action.
The statement added: “Repairs were made, a revised Declaration of Operational Compliance certificate was issued and the ride reopened just after 6pm.
“Although not reportable under RIDDOR (Reporting of Injuries, Diseases and Dangerous Occurrences Regulations), we have notified the HSE of the incident.
“We must comment on the actions of the operator and thank him for his swift and proportionate response to the incident.”
The Mart’s chief steward Donald Grey said it had been a small piece of plastic.
He said: “The council was happy. There was a safety check and a certificate was re-issued.”
The 140ft high Altitude was introduced to The Mart last year and has been entertaining thrill seekers.
The Mart will remain on Tuesday Market Place until Saturday, February 28.
The Mart opens at noon tomorrow and is closed on Sunday.
Next week it opens from 6pm, starting on Monday.
