Four people have been taken to hospital and 25 others treated for cuts and bruises following an accident on a ride at Alton Towers.
It happened when the front carriages of the Runaway Mine Train became separated and rolled back into the rest of the ride at the Staffordshire theme park...
The rollercoaster ride is one of the older attractions at the theme park.
Its description on the theme park's website invites customers to "rattle along the rickety rails and mine shafts, past trees and rivers, on a speeding locomotive that's out of control - and getting faster every second."
