Movie World has launched an investigation after four people had to be rescued from a rollercoaster yesterday.

The group was trapped 10 metres in the air for 90 minutes on the Scooby Doo Spooky Coaster.

It’s understood the ride stopped after one of the riders removed a piece of clothing, triggering a mechanism to stop.

Firefighters were required to safely unload the passengers because the ride stopped in the “high zone”.

A Movie World spokesperson described it as a “minor guest behaviour incident”.

“The guests on board were completely safe throughout the process and our expert team were in constant communication with them,” they said in a statement.

“The four guests on-board were all safely unloaded.

“The safety and wellbeing of our guests is our highest priority and our team conduct regular training with QFES on these scenarios and we would like to thank them for their assistance.”

It’s understood no one was injured in the incident.
