Dozens of people have been struck down with suspected virus after attending a Lego fan event in Bristol.
An investigation has now been launched into what happened at the unofficial Lego event, which took place in a sports centre over the weekend.
Organisers of the event told the Bristol Post they're 'devastated' after learning that people have fallen in with sickness and diarrhoea on Monday and Tuesday this week.
The Bristol Brick Show welcomed as many 4,000 people to the Action Indoor Sports centre in Hengrove. The annual event is the south west's biggest gathering of all things Lego and sees people from up and down the country.
Speaking to the Bristol Post, one of the organisers Nick Amos, from the Bristol Lego Users Group GertLug, said: "We had a great weekend, we had so many people saying about how much they loved what we did.
"We raised a total of £6,500 to be split between CLiC and Children's Hospice South West, and we've had families who attended and the displayers themselves still buzzing about how great the weekend was."
However, in the days following the event reports of vomiting and diarrhoea have come in from dozens of people, with exhibitors 'worst hit' according to the paper.
An unnamed source told the Bristol Post: "At least 40 people have been affected."
Amos added: "It's just such a shame after how successful the actual event was. We're all absolutely devastated.
"People are saying it was the venue, but I'm not sure. There are Norovirus bugs going around this year a lot, and it could just be as simple as one or two people brought it with them without knowing and it spread.
"What we had was 2,000 people attending each day in one space all day, so bugs love that sort of environment."
On the The Bristol Brick Show Facebook page, a statement read, in part: "We held the same event at the same venue last year with no known issues so are confident this is an unfortunate and isolated incident.
"As the organisers we are devastated that this has put a damper on an otherwise successful show obviously we wish everyone who is affected a speedy recovery.
"Thanks for your continued support and we hope your memories of the show are not by tainted by these events!"
A spokesperson from Bristol City Council confirmed that they had received reports and said inquires were underway.
