A man has died after a stabbing in a park.

Police were called to St Martin’s Gardens, in Camden, at around 1.35pm on Wednesday (April 10) following reports by the London Ambulance Service that a man had been found collapsed.

He has been named as 55-year-old Mark Carroll, from Camden.

He was treated by paramedics before being taken to hospital but despite efforts from the emergency services, he died later that day.

His family have been informed and are being supported by specialist officers. 

A post-mortem examination will be held on Friday  (April 12).

Initially, it was suspected that Mr Carroll had collapsed from a cardiac arrest but after further investigations by medical professionals he was found to have sustained a stab injury to his body, Scotland Yard said.

Officers were subsequently told by witnesses that they had seen a man making slashing motions towards the victim and his friend.

A 19-year-old man was arrested on suspicion of murder.

He was taken into custody, where he remains.

A knife has been recovered and sent for forensic analysis.

Police are appealing for members of the public to come forward with any information they may have.

Detective Chief Inspector Neil Rawlinson from the Metropolitan Police's Specialist Crime unit is leading the investigation. He said: “We have spoken to several people as part of our enquiries, however we believe there may be others who witnessed this incident, or the moments leading up to it, and I would ask them to come forward.

“This attack happened in a park, and I expect that a number of people would have been in the area.

"Were you in the vicinity of St Martin’s Gardens between 1pm and 2pm? Did you see anything? Were you approached by a man whose behaviour caused you concern?

“We are also continuing to review CCTV and would also ask anyone who has a video doorbell, or who was driving in the area with a dash cam, to please check their footage.

“It is vital that we establish what happened and recover all possible evidence.”

Superintendent Annmarie Cowley, who is responsible for policing in Camden, said: “First and foremost our thoughts are with Mark’s family and friends who have suffered an unimaginable loss.

“We know that this attack will also be of significant concern within the wider community, especially as it happened in such a public place.

“We are continuing to liaise with our partners, and you will see additional officers in the area over the coming days while we continue to investigate this tragic crime.

“I would ask that you speak with them if you have any information. It is only by working together that we can reduce violent crime, and we really need your help with this investigation.”

A crime scene remains in place.

Any witnesses should call 101 or post @MetCC quoting reference CAD 3650/10Apr.
