Staff at the Premier Inn called for assistance after a group of talent show hopefuls became rowdy and property was damaged.
Contestants, who had made it through to the boot camp stage of the show, were letting off steam after rehearsals when the party got out of hand.
It was the last night before they found out who had made it through to the next stage of the contest where they head to judges’ houses for further mentoring.
Television bosses have offered to cover the costs of fixing the damage to the hotel in Wembley, north west London, which is close to the studios where the live finals of the talent show are held.
A spokeswoman for The X Factor 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.”
A Scotland Yard spokesman said police were called to a minor disturbance at the hotel at 1.30am on Friday.
Staff said they were concerned they could not control a group of rowdy guests.
He said officers were satisfied they were not needed and left about 15 minutes later.
