An Afghan national, 22, was Tasered and arrested on suspicion of murder and attempted murder at Midhurst Gardens, Uxbridge, at 17:00 GMT on Monday, reported BBC.

The Home Office confirmed the arrested man entered the UK in a lorry in November 2020, was granted asylum and leave to remain in 2022, and does not live in Home Office accommodation, the British media reported.

The Metropolitan Police said its officers attended the scene alongside the London Ambulance Service, who treated three victims at the scene for stab injuries.

Speaking on the deceased person, the police said in its statement: "A 49-year-old man was treated at the scene for stab wounds. Despite the best efforts of the emergency services, he died at the scene."

Chief Superintendent Jill Horsfall who leads policing in Uxbridge has said: “This was a shocking and senseless act of violence that has left one man dead and two others injured. Our thoughts are with the victim’s family and friends at this unimaginably difficult time.

“The incident will have understandably caused concern to the local community, I have deployed multiple officers to the local area, they will be here throughout the week to provide reassurance while detectives work intensely to piece together the circumstances.

“I understand that there has been a lot of speculation online following on from this incident, we ask that you rely on us for information, and that you do not share sensitive footage.

"If anyone saw, or has any information about the incident, then please come forward to police. We appreciate any information that you may have.

"There will be a crime scene and a heavy police presence within the area over the next few days, I thank residents for their patience.”
