A 21-year-old man has been charged with the murder of a young actor who was stabbed to death in south-east London.
Rob Knox, 18, was stabbed in a fight outside the Metro Bar, Sidcup, in the early hours of Saturday. His parents said he was a kind and thoughtful son.
Unemployed Karl Bishop is accused of killing the teenager and with wounding five other people.
Mr Bishop, of Carlton Road, Sidcup, will appear in Bexleyheath Magistrates Court on Tuesday.
A post-mortem examination held at the Royal Princess Hospital, Farnborough, revealed that Mr Knox died of internal bleeding as a result of stab wounds.
On Sunday, his father Colin Knox read out a statement to journalists which said: "It's impossible to convey the sadness and loss that we all feel but we now realise Rob touched many people's lives.
"Rob was happy, outgoing and a fun person to be with. He was the social hub of his large circle of friends.
"Rob always put everyone before himself, was always the first person to stand up against wrong. He achieved so much in his short life."
The 18-year-old, who had a small part in the new Harry Potter film, was the 14th teenager to die violently in London this year.
