15 year old Emily Nakanda has quit the X Factor amid allegations of assault.

A spokesman for the show has confirmed the 15-year-old Londoner has withdrawn herself from the show after the Sun uncovered footage of her allegedly assaulting another teenager. The footage that was filmed on a mobile phone apparently shows her putting a blonde girl in a headlock and then swinging another girl by her hair, before hitting her several times and shoving her to the ground.

An X Factor statement confirmed her exit, explaining: "In response to the stories in the papers this week regarding Emily Nakanda we have conducted our own investigations into the matter and we can confirm that she has chosen to withdraw herself from the competition with immediate effect."

Emily's family are disappointed by her behaviour while Sharon Osbourne, Emily's mentor on the X Factor, is deeply saddened by the whole situation.

Nakanda's exit will not affect voting on the show.

There is also another video that The Sun uncovered this week which appeared to show Nakanda threatening to gouge a boy's eye out with a knife.
