The Health and Safety Authority is due at Tayto Park tomorrow following an accident at a Halloween attraction in which nine people were injured. 

The incident at Tayto Park in Ashbourne happened last night when a staircase collapsedduring an after-dark, Halloween-themed event.

Gardaí were called to the park shortly after 8pm. A garda spokesman confirmed that nine people were taken to hospital.

Most sustained cuts and bruises but one person is understood to have fractured a bone. All nine people have been discharged from hospital. 

A spokeswoman for the park said those caught up in the incident were taken to hospital as a "precautionary measure".

This morning, the park said the lower portion of a permanent staircase leading to the 'House of Horrors' attraction gave way.

It added: "The management of Tayto Park will co-operate fully with the investigation as the safety of our guests is paramount."

The park remains open today.

Rian O'Kelly said she visited the park with her 13-year-old sister and her two young friends yesterday.

In an interview with BBC Radio Ulster's Sunday News programme, the 25-year-old from Dublin said the stairway was in two sections and she had just stepped onto the middle landing when the stairs behind her "vanished" from sight.

"We heard this big creaking noise and we thought it was part of the show, like trying to be scary, but then, next of all, people directly behind us just dropped and the whole staircase collapsed."

"Obviously everyone got really afraid and everyone started crying and screaming and stuff and running because we thought we were going to drop down as well.

"All the younger children, and adults even, were screaming and crying. It really was very scary and quite ironic, that we were supposed to be going into a house of horrors," said Ms O'Kelly.
