Rollercoaster at Movie World to remain closed after malfunction left thrillseekers dangling

A Movie World rollercoaster will remain closed today as the Gold Coast theme park investigates a malfunction that left patrons dangling for 90 minutes.

Twenty thrillseekers were left stranded at the top of the Arkham Asylum ride yesterday afternoon after carriages became stuck.

It took Movie World staff and firefighters more than an hour and a half in the 30C-plus heat to free them.

Movie World general manager Greg Yong said a "mechanical issue with the chain" had caused the roller coaster to stop.

Mr Yong said the ride would remain closed while the company investigated what happened.

"We don't see it being closed for an extended period of time but I can't really tell you any more until we do a full analysis," he said yesterday.

"These kind of mechanical issues are something that takes a little bit of time for us to investigate."

The breakdown came just weeks after the nearby Dreamworld theme park reopened following a rigorous safety review over the deaths of four people when rafts on the Thunder River Rapids ride collided on October 25.

Dreamworld owner Ardent Leisure has announced that the ride would be demolished and a permanent memorial to the victims erected.

Today, two of the themepark's "Big 9 Thrill Rides" were re-opened after a multi-level safety review.
