A young man, tragically killed in a stabbing at Primrose Hill, has been identified for the first time.

Finbar Sullivan, a 21-year-old who directed rap music videos, succumbed to knife wounds sustained during an altercation at the London park, where he was pronounced dead on the scene yesterday evening.

Videos circulating on social media captured the chaos, as groups of men engaged in a daylight brawl, much to the horror of park-goers who had gathered to enjoy the sunny weather.

In one clip, a youth is seen brandishing a knife, threatening another individual before retreating quickly, adding to the alarming scene.

Another social media post reveals paramedics working to save a person on the ground, highlighting the urgency and desperation of the situation.

Authorities confirmed late last night that a 21-year-old man had died at the location. No arrests have been reported as of yet.

Another man, believed to be in his 20s, was also stabbed. He was found by officers nearby on Regent’s Park Road. 

He was taken to hospital by paramedics. His injuries are not believed to be life-threatening or life-changing.

Detective Inspector Andy Griffin, who is leading the investigation, said: ‘Finbar’s family have suffered a devastating loss and our thoughts are with them as they navigate this very challenging time.

‘Our investigation is progressing at pace and we are following several lines of inquiry. This incident occurred in a busy, public park and there may be many witnesses who can help us piece together what happened.

‘We are aware of footage circulating on social media around the time of the incident, and urge anyone who has any information, including photos or videos, which could support the investigation to urgently contact us.’

Officers and ambulance crews confirmed last night that they were called at around 6.40pm to reports of a fight at the viewpoint next to Regent’s Park.

It came as the UK saw the warmest day of the year so far and people flocked to the park to enjoy widespread sunshine.

One witness to the fight told the Daily Mail: ‘The park was just so busy, I had gone with my mate after work and it was literally the busiest I have ever seen it because of the weather and it being Easter holidays.

‘Then suddenly we heard this commotion from behind us, and a big brawl kicked off – people were throwing punches, people were screaming at others to stop.

‘There were lots of people involved in the initial fight, most of them looked like teenagers about 18 or 19.

‘Then a group of three people ran off past us and one of them said to the other “you’ve been sheft [slang for stabbed] mate” and you could just see this massive red patch on his shirt.

‘After that a massive group of people began crowding around someone on the floor where the fight had been and you could see from people’s reactions it was not good. Lots of people had their head in their hands and just looked very distressed.

‘About an hour later the police came and told everyone they had to leave because it was now a crime scene.’

Superintendent Matt Cox said: ‘This is an utterly tragic incident and our thoughts remain with the man’s family and loved ones.

‘I would like to reassure the local community that the investigation is unfolding at pace and an increased police presence will remain in the area while we carry out enquiries.

‘I would appeal for anyone who was in the area at the time and has any information that could help my officers to come forward.’

A London Ambulance Service spokesman said: ‘We were called at 6.41pm to reports of an incident in Primrose Hill.

‘We sent a number of resources to the scene, including ambulance crews, an advanced paramedic practitioner, incident response officers, and we deployed crews from London’s Air Ambulance.

‘Very sadly, despite the best efforts of our crews, one person was pronounced dead at the scene. A further patient was taken to a major trauma centre.’

Anyone with information that may assist police is asked to 101, quoting CAD 6448/07Apr or Crimestoppers, anonymously, on 0800 555 111.

The fight in Primrose Hill last night is just the latest incident in a surge of anti-social behaviour that has been plaguing London since Sadiq Khan became mayor.

Sir Sadiq has maintained that the capital – often dubbed ‘Lawless London’ – is not perfect but that it remains a safe city.

However, a closer look at the data shows that a range of crimes, including theft from the person, sex offences, drugs and violent crime, have dramatically increased from when he first came to power in 2016.

Theft from the person has increased by 140 per cent from 35,570 in 2016/17 to 85,465 in 2025/26.

In 2024/25, the year Sir Sadiq was re-elected, it had even skyrocketed to 101,053.

Elsewhere, sexual offences have risen by 55 per cent from 17,491 in 2016/17 to 27,074 in 2025/26.

Drug offences have risen by 34 per cent from 40,652 in 2016/17 to 54,291 in 2025/26.

And violence against the person has soared by 51,086 incidents 27 per cent from 191,691 in 2016/17 to 242,777 in 2025/26.

The figures, based only on crimes reported to the Metropolitan Police, do not factor in how London’s population has grown over the same time.

Official estimates suggest the capital’s headcount has risen from 8.7million in 2016, the year Sir Sadiq was elected, to just shy of 9.1million in 2024 – the most recent year.
