Merlin Entertainments, who own the park, had also closed three other rollercoasters at other theme parks for safety reasons.

Dragon's Fury and Rattlesnake rides at Chessington World of Adventures are still closed.

A Chessington spokeswoman said its two rides were safe, but staff working on them needed further training before they could be reopened.
