The unnamed guard is reported to have manhandled and verbally abused fans while trying to control crowds, the Daily Mail reports.
The incident occurred when fans tried to meet contestants such as Jahmene Douglas and Jade Ellis when they returned from rehearsals. The crowd was said to have tried to get into the hotel to talk to the contestants.
The security guard in question was photographed attempting to stop two teenage girls from entering the hotel, and is alleged to have shouted 'f**king c***s' at the crowd.
A spokesperson for The X Factor confirmed reports of the arrest, but denied that there was any verbal abuse directed towards fans.
"A member of the team was arrested but no charges were brought and he was let off with a caution", he said.
"Young fans were present but it was a photographer who called the police and complained about abusive language, not one of the fans," he added.
This is the latest controversy surrounding The X Factor and the Corinthia Hotel. Last week, contestants Lucy Spraggan and Rylan Clark were removed from the premises after their drunken behaviour outside the hotel.
