Singer Harry Styles was forced to pause a live concert in order to protect the crowd after eight audience members fainted.
Video footage shows the 28-year-old singer asking the crowd to move back slowly to stop fans being crushed against the handrails.
The former One Direction star said: "I am very excited to be here, and I know today is going to be an amazing show.
"But the most important thing is that everyone in here is safe, because there are a lot of people in here and it's warm."
