Alton Towers will remain closed until the cause of a rollercoaster crash that left 16 people injured is discovered, the theme park's boss has said. The Staffordshire attraction's gates are shut for a second day while the Health and Safety Executive investigates Tuesday's crash. Nick Varney, of Merlin Entertainments, which runs the park, said it could only reopen when they knew the problem was isolated to the rollercoaster.
