A "mechanical failure" caused 9 riders to become trapped for up to 8 hours on the Tsunami rollercoaster at M&Ds theme park in Lanarkshire, Scotland.
The coaster was on a section of track 60 feet above the ground when the incident occurred at around 4.15pm on July 3, 2011, trapping a group of riders aged between 9 and 49. Strathclyde Police and other emergency services were called to the scene, and were able to free the guests without any injuries being caused.
A spokesperson for the park insisted that riders were never in danger, with park staff able to carry water up to the guests to keep them hydrated during the incident.
Similar incidents have affected M&Ds during the last few years, but none have resulted in serious injuries. In 2005, 6 riders were trapped on the Vortex rollercoaster when it became stuck. Then, in June 2009, 6 riders were stranded on the Tornado ride when high winds triggered safety systems.
