A man has been charged with murder after a 21-year-old was fatally stabbed in north London, police said.

Finbar Sullivan died on Tuesday 7 April after the alleged attack in Primrose Hill. On Sunday, Oliuwadamilola Ogunyankinnu, 27, was charged with murder.

The Metropolitan police said the 27-year-old, who was arrested on Friday, will appear at Stratford magistrates court on Monday. A 25-year-old man arrested on suspicion of assisting an offender has been released with no further action, police said.

Sullivan, 21, a filmmaking student, was stabbed to death at the view point in Primrose Hill in the early evening on Tuesday. His father, Christopher Sullivan, 65, previously said his son had gone to the area to use a new camera he had got for his birthday.

“This is the worst tragedy I could ever imagine,” he told the Daily Mail. “I’m so broken-hearted, I can’t believe it. He was the most beautiful, lovely, outgoing, loving boy. He was just a really lovely person.”

Sullivan said his son had ambitions to follow in the footsteps of his grandfather, cameraman Michael Seresin, who worked on Harry Potter and the Prisoner of Azkaban and Rambo III.

Officers are urging anyone who may have relevant information to upload it to the Met’s online major incident portal or to call 101 and quote reference 6448/07Apr.
