: "We were there. All we heard was a loud bang and screams, we were the next to go in. It’s very sad hope everyone is ok.
Another added: "I witnessed it. It was shocking. My husband had to hold the stair rail up."
A third recounted the incident, saying: "Was there tonight, we were next group to enter the house of horrors- hope all are ok and no serious injuries- the staff handled the incident well, there was no sense of major panic, they closed the house immediately and they refunded everyone their €20 entry fee, all other rides were operating."
Others who witnessed the incident said they had been afraid the collapse could have had a much more serious outcome.
Two ambulance crews were called to the scene about 8pm.
