Those trapped on the Arkham Asylum Coaster ride were seated in chairs suspended from the ride. Most were easily rescued, but four could only be reached by emergency personnel using a ladder platform, according to a spokeswoman for Queensland Fire and Emergency Services. No one was injured.

The latest incident at the Warner Bros. Movie World park, owned by Australia's Village Roadshow Ltd, follows a deadly accident at Dreamworld theme park owned by Ardent Leisure Group in October, 2016.
