Alton Towers will remain shut for a third day today after Tuesday’s rollercoaster accident.

The theme park in Staffordshire said it will be posting all updates on the closure on both its website and social media channels.

Sixteen people were hurt, including four seriously, in the crash between cars on the £18 million, 14-loop Smiler rollercoaster.

Shares in Merlin Entertainments, which owns the theme park, have fallen just over 2.6% since the accident, wiping about £100 million off its stock market value, the BBC reported.

It quoted an unnamed analyst as estimating the park could be losing £500,000 for every day it stays closed.

Merlin Entertainments chief executive, Nick Varney, said the park would reopen only when the investigation into the incident had concluded, but did not give a time-frame.

The Alton Towers website says: “Alton Towers Resort is currently closed following Tuesday’s incident. The investigation into this is ongoing and we will release further details regarding the reopening of the theme park as soon as we can.”

Tickets pre-booked for Alton Towers will be accepted at Warwick Castle, Thorpe Park, Chessington World of Adventures and Legoland Windsor.
