Rob Knox Tribute

18-year-old Rob Knox was killed outside the Metro bar in Sidcup, southeast London, as he tried to protect his younger brother, Jamie, from a man armed with two knives.

The actor, who plays the Hogwarts student Marcus Belby in the forthcoming film Harry Potter and the Half-Blood Prince, was the ninth teenager to be stabbed to death in London this year.

He was a member of the same rugby club as Jimmy Mizen, who was stabbed to death two weeks ago at a bakery in Lee, southeast London.
