POLICE are pleading for a key witness to come forward after the murder of a man, 21, at a famous London beauty spot.
Finbar Sullivan tragically died after being stabbed at the viewing point at Primrose Hill, North London, on Tuesday evening.
Met detectives are now appealing for a young woman or teenager to help solve the tragic case.
The woman was captured on film recording a fight in the park shortly before the murder.
In a statement, cops said: “The footage she filmed is vital to ongoing enquiries and will help officers piece together the sequence of events.”
She has not committed any offences and is being treated as a significant witness.
Footage shows her wearing a pink vest, blue denim shorts and black trainers.
Detective Inspector Andy Griffin, who is leading the investigation, said: “My team continues to pursue several urgent lines of enquiry to establish why Fin tragically lost his life.
“I believe this woman’s account of events, as well as the video she captured, will provide vital evidence. To reiterate, she has not committed any offence but we are urging her, or anyone who may know her, to come forward and assist our investigation. We need to speak to her as soon as possible.”
