One person is in hospital with 'serious injuries' after three people were thrown from a ride at a Winter Wonderland event.
Eventgoers spoke of hearing a "massive bang" before people came off the ride shortly after 5pm on Saturday in Gorsedd Gardens, in Cardiff.
Two patients were taken to the University Hospital of Wales and one is still there as of Monday afternoon, according to the Health and Safety Executive (HSE).
A spokesman for the watchdog said: “HSE is investigating reports of serious injuries on a ride at Winter Wonderland in Cardiff. Three people were thrown from the ride. One currently remains in hospital and is being treated for their injuries.”
Seren McCallum-Weller was at Winter Wonderland on Saturday celebrating her birthday with her family.

The 13-year-old told WalesOnline: "I was on the Ice Skater ride with my cousin. We were just having a fun time then we suddenly heard a massive bang. I didn't know what it was.
"We looked behind us and the ride was still going and then we saw a lady on the floor. We then saw a second lady who was pushed into the railings and the railings had moved. She was lodged in between the ride and the railings.
"I think a third lady was also thrown into the railings. There were a few children on the ride who were no older than 11 or 12."
Seren said the ride involves several clusters of around four seats each, which spin and move diagonally "very fast". She said staff tried to stop the ride as soon as they could but it took a few minutes to slow down.
She added: "The ride was slowing down and it came to a stop about one or two minutes after it happened. The attendants were trying to stop it straightaway.
"One of the ladies had damaged her head and there was blood. I think she possibly broke her ankle as well. I think [one of them] was unconscious. I was panicking. I saw one woman get up and as I was leaving I heard one of them crying. I hope the ladies are okay.
"You see things like this happen on YouTube and hear them happening to other people but it's scary when it happens to you. It has scared me and I'm giving theme parks and rides a miss in the future."
It was understood that Winter Wonderland opened on Sunday but the Ice Skater ride was not running.
A spokesman for Cardiff’s Winter Wonderland said: “We are aware of an incident that occurred on the Ice Skater ride at Cardiff’s Winter Wonderland on the evening of Saturday, November 26. Safety is always a priority for us and a full investigation into the incident is now taking place.
"We, as the event organisers, are working closely with the ride owner/operator and all relevant organisations to investigate. The ride will remain closed during this time.”
Cardiff council said it would support "any investigations that will be undertaken in due course".
