Thug sows Amir's belongings

would-be car-jackers in Digbeth, Birmingham, in the early hours of Monday morning and drove off which resulted in a youtube video where a masked thug has threatened boxing champion Amir Khan that he would rip his head off. Police are investigating the video which followed reports. Before fleeing the scene, Amir managed to knocked one of thugs out with a flurry of blows.

In a video posted on social networking sites yesterday a masked man gave his own foul-mouthed version of events and shrieked a series of threats to the Bolton-based champ. He screams into the camera: 'I'll rip your f****** head off. You know the truth, we know the truth. You got knocked the f*** out.

'Next time you can bring an army. Who gives a f*** if you're Amir Khan. You're not a hero here, you're a zero.'

The video, which looks like it was filmed in someone's living room, came
after the reported punch-up in Adelaide Street, Digbeth, when the boxing brothers were said to have been targeted by robbers, who were trying to steal Amir's £100,000 Range Rover.

In the two-part video, the masked man holds aloft belongings including a bag, wallet and car keys, which he claims belong to the former world titleholder.

In an official statement last night, Detective Inspector Dawn Miskella said: 'Police are investigating reports of an alleged criminal incident on Adelaide Street, Birmingham at around 1:23am on Monday 8 October.'
