Mass fainting and vomiting erupts at Las Vegas concert - here's the heartbreaking reason it happened
A free concert in Las Vegas reportedly descended into chaos over the weekend after extreme heat caused a number of attendees to become ill, by fainting and vomiting in the mass crowds.
Fans attending Sleeping With Sirens’ performance on Saturday at the Fremont Street Experience said they were squeezed tightly together as they gathered to watch the rock band. The outdoor venue quickly became overwhelming as temperatures climbed above 100°F.
Why were people falling in?
The combination of soaring heat, overcrowding and limited access to water for those stuck in the middle of the crowd led to distressing scenes, with some attendees saying they felt trapped and unable to leave the event.
As conditions worsened, panic began spreading through the audience. One concertgoer said people around her were collapsing one after another.
“People were just dropping like flies right in front of me,” she claimed.
Speaking to KLAS News, another attendee claimed the organisers were not prepared for the size of the crowd that turned up.
“I don’t think they were equipped for the crowd that was going to be there, and by the time they realised it, it was too late.
“It was getting worse and worse. It was so bad, people were standing in the middle of the metal detectors," she added.
Another fan described how the crowd became increasingly uncomfortable, saying she and those around her began feeling the pressure as people struggled in the tightly confined space, as they contended with both spatial constraints and the heat.
“We stayed for about three and a half, four songs, and we just started getting crunched more and more,” she explained.
Apparently, the excitement of attending the concert quickly turned into concern after seeing people become unwell around her.
“There were people passing out next to us, behind us, everywhere,” she claimed.
The Fremont Street Experience, a pedestrian mall and outdoor entertainment area where the concert was held, later responded to the incident.

In a statement to KLAS News, the venue said guests were allowed to bring sealed plastic bottles into the concert area, while certain containers were restricted.
“Guests attending Fremont Street Experience Special Events are welcome to bring sealed, plastic bottles into the concert area.
