Four rides shut following Alton Towers Smiler crash

Four rollercoasters at three theme parks have been shut after a crash on the Smiler ride at Alton Towers.

Sixteen people were injured, four seriously, in the crash on Tuesday.

The Smiler has been shut for investigation since, and Merlin Entertainments, the people that run the parks, say that their 'Saw' ride at Thorpe Park, will also be shut "for the foreseeable future".

Dragon's Fury and Rattlesnake rides at Chessington World of Adventures have also been closed.

A Chessington spokeswoman said its two rides were safe, but staff working on them needed further training before they could be reopened, which she hoped would not take more than a few days.

Merlin Entertainments said it planned to reopen Alton Towers in the next few days.

Accidents on rollercoasters are extremely rare.

The company say they have added safety procedures to "reinforce the safe operation of our multi-car rollercoasters" which were "effective immediately".
