Two more teenagers have been arrested over the fatal stabbing of a teenager on New Year's Eve - and police have said there is "no indication" of a racial motive.

Harry Pitman, 16, was killed on Primrose Hill at around 11.40pm on Sunday (December 31) after going with friends to watch the fireworks.

Police were called and provided first aid before paramedics arrived, but despite the efforts of emergency services, Harry died at the scene shortly before midnight.

A 16-year-old boy was arrested at the scene on suspicion of murder and later released on bail pending further enquiries.

Detectives from the Met’s Specialist Crime Command yesterday (January 2) arrested a 15-year-old boy on suspicion of murder and an 18-year-old man on suspicion of affray.

Both were taken to central London police stations where they remain at this time.

Detective Chief Inspector Geoff Grogan, who is leading the investigation, said: “Harry had been with a group of friends near the viewing platform on Primrose Hill where they had gathered to celebrate the New Year and watch the firework display. It was there that Harry became involved in an altercation that would have devastating consequences.

“We are aware of speculation, especially on social media, that the attack may have been racially motivated and I can confirm that there is no indication of a racial motive.

“Despite having made three arrests, I am still very keen to hear from anyone who has footage or information that could assist our investigation.

“Similarly, I would like to thank everyone who has come forward so far – the help that you have given makes a difference.”

Chf Supt Andy Carter, who leads policing in Camden, said: “New Year’s Eve at Primrose Hill is a celebratory event that everyone should have returned safely home from.

"I am deeply saddened at the needless loss of another young life to knife crime.

“Thousands of people attended the event and it is testament to public spirit that some of those people have come forward to assist our Specialist Crime colleagues by providing information.

“We are aware of local concerns relating to the park. As a partnership, we take the safety of park users seriously, and we will continue to work with Camden Council and Royal Parks to address local issues.

“Local people will notice a heightened police presence to provide reassurance in the Primrose Hill area in the coming days. If you have concerns please do approach officers and speak with them, or, if you prefer, contact your Neighbourhood Policing Team who would be happy to help you.

“My thoughts and prayers are with Harry Pitman’s family.”
