A bolt recently fell from the structure of Blackpool Pleasure Beach’s Big One rollercoaster, it has emerged.
The Sun newspaper quoted a visitor as saying it landed within “inches” or her child.
A spokesman for the amusement park said that the bolt fell from the return bend of the ride.
He added: “We believe it landed on the roof of a building before coming to rest on the floor by the family.”
The incident occurred on 9 August, with the ride re-opening later in the day following safety checks.
