Ten males aged in their teens have been arrested after a teenager was knifed to death in Montrose Park, Scotland Yard said.

Police are appealing for information after officers were called at 5.54pm on Bank Holiday Monday to the park near Burnt Oak following reports of a group of males fighting.

An 18-year-old male was found suffering from a stab injury in a tennis court area of the park.

He was treated by London’s Air Ambulance and London Ambulance Service at the scene but despite the best efforts of paramedics, he was pronounced dead at 7.19pm.

A post-mortem examination is expected to be held on Thursday and while officers believe they know the identity of the deceased, efforts to inform his next of kin continue.

On Tuesday, the Metropolitan Police said 10 males have been arrested in connection with the incident on suspicion of offences including affray and murder.

Eight of them have been released on bail with two remaining in custody whilst the investigation is ongoing.

Detective Chief Inspector Claire Hine, who is leading the investigation, said: "I'm really thankful for the witnesses who have already come forward and helped with our investigation.

"I'm now appealing for more people to come forward who saw the incident happen and the moment the victim was attacked. Any piece of information, videos, images could assist us in understanding as to what led to this violent incident where a young man has lost his life.

"The park was busy at the time with a lot of people enjoying the sunny day. If you have any information, please contact us immediately."

Deputy Leader of Barnet Council Cllr David Longstaff described the incident as a "senseless and brutal attack".

He said: “I join the people of Barnet in expressing my deepest condolences to the family and friends of the young man who tragically lost his life in Montrose Playing Fields on Bank Holiday Monday.

"I thank the police for swiftly making a number of arrests. Barnet Council will continue to work with the police and community groups to keep our parks and streets as safe as possible for everyone to enjoy.”

Any witnesses or those with information, video or images that could assist officers are asked to call 101 reference CAD 5436/31 May.
