«Police had to be called to the hotel in north London where X Factor boot-camp contestants were staying.
Staff at Wembley’s Premier Inn called police at about 0130 BST to deal with the group of the talent show hopefuls. The contestants were to find out who had made it through to the next stage the morning after.
An X Factor spokesman said: “Contestants had an opportunity to relax after a week of intense rehearsal and performance.
“We have spoken to the individuals concerned, who have apologised for their behaviour.”
