Detectives appeal for potential key witness in Primrose Hill murder probe

Met detectives are appealing for a key witness to come forward following the murder of Finbar Sullivan in Primrose Hill.

The young woman or teenager was captured on film recording a fight in the park, which is believed to have occurred shortly before the incident. 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.”

Officers were called at 18:41hrs to reports of a fight at the view point in Primrose Hill.

Upon arrival, police and paramedics from the London Ambulance Service found Finbar, 21, with stab wounds. Despite the efforts of emergency services, he sadly died at the scene.

Another man, believed to be in his 20s, was found nearby on Regent’s Park Road. He was taken to hospital by paramedics with stab wounds. His injures have since been confirmed as non-life-threatening and non-life-changing.

No arrests have been made at this stage and the investigation continues.
