Harry Potter actor killed in Sidcup knife attack while coming to the aid of his younger Brother

Friends said the murder victim, who they named as 18-year-old Robert Knox, worked as a film extra and was due to appear in the new Harry Potter film coming out in November.

He died after intervening on behalf of his younger brother Jamie Knox, 16, when two men, including one said to be armed with two knives, came into the bar.

A fight erupted inside the Metro bar, next to Sidcup train station, on the south-east London-north Kent border, before spilling outside onto the pavement and into the road.
Robert - who went to the same Sidcup Rugby Club as 'gentle giant' teenager Jimmy Mizen, who was murdered in nearby Lee two weeks ago - was pronounced dead shortly after the incident at around 12.07am.

The stabbing happened just yards from the shoe shop owned by Jimmy's parents in Sidcup High Street.

Scotland Yard confirmed a young man died from knife wounds, a 21-year-old man suffered stab wounds to his chest and a 16-year-old youth also had knife wounds to his chest.

A police spokesman said: "A man aged 21 has been arrested on suspicion of murder. He is being held in custody."

Robert, who lived with his family in nearby Swanley, Kent, used to be a student at Hurstmere School, Sidcup.

Friends and family were leaving floral tributes in Station Road, Sidcup, today.
