Alton Towers has been closed to allow an investigation into a rollercoaster accident which left four people with serious injuries.
Two carriages crashed on the Smiler ride at the Staffordshire theme park yesterday, leaving some passengers trapped for more than four hours.
Two men, aged 27 and 18, a woman aged 19 and a girl, 17, suffered serious leg injuries in the crash.
Another 12 people – six men and six women – required medical treatment.
They included a man in his 20s who suffered neck and abdominal injuries.
An Alton Towers spokeswoman said it was hoped the park would open again on Thursday.Customers with tickets for Wednesday can change them to another day or request a refund through the attraction’s website.
Nick Varney, chief executive of Merlin Entertainments which runs the park, said: “This has been a terrible incident and a devastating day for everyone here.
“The safety of our visitors is our primary concern. The park will remain closed until we understand better the cause of this dreadful incident.”
Shares in the company fell by almost 3.5% to just over 444p following the incident which occurred at about 2pm.
The £18 million rollercoaster, which claims a record-breaking 14 loops, has been closed on two occasions because of safety concerns since opening two years ago.
