A 21-year-old filmmaking student who was stabbed to death in Primrose Hill "can never be replaced", his father has said.

Finbar Sullivan was stabbed in a fight near the viewing point at the north London beauty spot shortly after 18:30 BST on Tuesday and died at the scene.

Christopher Sullivan told the Daily Mail his son wanted to become a cameraman like his grandfather Michael Seresin - who worked on Harry Potter And The Prisoner Of Azkaban and Rambo III - and had gone to the park to use a camera he was given for his birthday.

"This is the worst tragedy I could ever imagine," the 65-year-old told the newspaper, adding that Finbar was his only son.

Sullivan described his son as a "beautiful, lovely, outgoing, loving boy".

Finbar was a student at the London Screen Academy and produced music videos for drill rap artists under the name Sully Shot It, the Daily Mail reported.

Sullivan said his son was "not a gang member", but a "groovy 21-year-old who loved movies and making films".

Ellen Kinnally, friend of Sullivan and PR professional from New York, told The Times Finbar had been unwell before he was killed, but had been "getting better".

She said: "He'd gotten very ill recently and everyone was so worried about him. It affected his eyesight, but he was getting better. He was a visual person."

During the fight on Tuesday, a second man in his 20s also injured. He was taken to hospital for non life-threatening stab wounds.

The Met appealed for anyone with information, pictures or videos from the scene to come forward. No arrests have been made.
