Caroline Flack has reported a Twitter user to the police after they sent her a terrifying picture of a girl holding a knife in her hand.
The Xtra Factor presenter re-Tweeted the photo from harrynostrils69 - who appears to be a fan of her ex-boyfriend Harry Styles - to London's Metropolitan Police and her 854,062 followers yesterday.
'Acceptable tweet? @metpoliceuk,' she wrote.
It's not the first time that Caroline, 32, has been targeted by One Direction fans - when she was dating Harry, 18, she received hate mail and death threats over Twitter.
After she reported harrynostrils69, the user's profile was removed from the social networking site.
'We're investigating,' police tell The Sun.
