The father of the teenage HARRY POTTER star who was fatally stabbed outside a London bar on Saturday morning (24May08) has been remembered as a "kind and thoughtful" son by his grieving parents.

Rob Knox, who plays Hogwarts student Marcus Belby in the upcoming Harry Potter And The Half-Blood Prince, died after reportedly trying to defend his younger brother Jamie from an attacker outside Metro bar in south east London.

In a statement, the tragic actor's parents, Sally and Colin Knox, said, "Rob was kind and thoughtful and would always help out others. He would always spent his last penny on other people instead of himself. The life and soul of the party, he was very outgoing, loved sports and would always strike up conversation with people.

"He was respectful to others and adored by all his family and friends. He was an asset to the family."

Knox had just completed filming of the latest Harry Potter film and had signed on to appear in the seventh film in the franchise, Harry Potter And The Deathly Hallows, when tragedy struck.

As WENN went to press police were still questioning a 21-year-old suspect.
