A 49-year-old man, named locally as Wayne Broadhurst, was treated by paramedics but died at the scene. A second man, aged 45, was hospitalised with life-changing injuries, and a 14-year-old boy sustained non-life-threatening stab wounds, police said.

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

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.

He was taken to hospital as a precaution but has since been taken into police custody, according to the Metropolitan Police.

The attack is not being treated as terrorism, and detectives are working to establish any relationship between the suspect and the three victims.
