Robert Knox, 18, who appears in the next *Harry Potter* film alongside Daniel Radcliffe, was stabbed to death in Sidcup, south-east London, early on Saturday.  
  
Knox, who appears as Marcus Belby, was stabbed trying to defend his younger brother, Jamie, from an assailant outside of a club.  
  
According to theage.com, the police deem that the alleged killer was thrown out of the club because of a scuffle over a stolen mobile telephone 10 days prior before returning late on Friday night. It is not clear what occurred in the moments to follow, but reports state that Robert Knox emerged from the club shouting, "You pulled a knife on my brother."  
  
"All I remember was seeing him stabbed in the chest. I ran over and me and my mate Tarik both tackled the black man. . . . As I tried to grab the knife, I didn't realize he had another in his hand. . . .," one teenager told the *Sunday Times*. "There were a lot of other people helping . . . then I walked around the corner from the bar. That's when I saw Rob - it's too horrible to describe what I just saw. It was just red blood," he continues.  
  
Knox's death makes him the 28th teenager killed in Britain this year, and the 10th in London to die from stab wounds. This huge rise in the amount of teenagers being killed on the streets of London leads senior officers to believe it is the leading threat facing the capital after terrorism.
