The thrillseekers were helped to safety from the ride after it got stuck 180ft up.

The ride came to an abrupt stop mid-way forcing passengers to climb down the side of the tracks.
Witness Jack Hughes, 18, told MailOnline: "The carriage is completely stuck at the top and it isn't going.
"About six staff all went up with harnesses and started taking the riders off.
"People were gathering around and looking up at the ride. There were a few staff from the nearby shops that were looking up at it as well."
The coaster is just yards away from the Smiler ride - where two teenage girls each lost a leg and 14 others were injured in June 2015.
