Nine people have been taken to hospital after a stairway collapsed at Tayto Park last night.
It's understood the stairs that collapsed is part of a newly opened 'House of Horrors' attraction which had been developed for Halloween.
Eyewitness reports also claim at least two ambulances were called to the scene, while a spokesperson says customers had been brought to hospital as a precaution.
The park remained open following the incident and is due to open again today.
Tayto Park have released a statement, saying they will "co-operate fully" with the HSA investigation.
