Police officers moved quickly to take down a man who allegedly threatened to kill pop star and actress Hilary Duff during her appearance on a Canadian TV show.

Duff was being interviewed Tuesday by MuchMusic host Leah Miller on Live @ Much when a man in the crowd outside the studio started shouting at the 19-year-old star. According to an eyewitness, the unidentified man vowed to kill Duff, prompting several police officers to tackle him.

"The cops slammed his face into the pavement," said someone who saw the incident. "He was bleeding."

The commotion happened just metres from an outdoor platform where Duff later stood to greet fans who surged forward for autographs and pictures.

Last November, police in Manhattan Beach, California, arrested 18-year-old Maksim Miskovsky for stalking and threatening to kill Duff.  A month earlier, Duff and her then-boyfriend Joel Madden  filed for restraining orders against Myakovsky and his 50-year-old roommate David Joseph Klein.

Myakovsky pleaded no contest to the charges in January and was sentenced to 117 days in jail and five years probation.

Why do the crazy folk love Hilary Duff?!
