Officers were called at around 9 o’clock last night to reports of a man suffering injuries outside a property in Typhoon Way.
The 42 year old man died at the scene.
A woman was arrested on suspicion of making threats to kill.
The investigation is led by Detective Chief Inspector Mike Nolan in Specialist Crime. He said: “Our investigation is in the very early stages. Specially trained officers are supporting the victim’s family and they have our assurances that officers will do everything we can to support them and bring to justice whoever is responsible for this senseless act of violence.
“We have spoken to a number of people, but I still want to hear from anyone who may have captured footage via their doorbell, car or camera, to come forward and speak to us as quickly as possible.”
Chief Superintendent Andy Brittain, lead for policing in Sutton, said: “Local people will see an increased presence in the area as our colleagues in Specialist Crime investigate.
“Police and the public must work together to tackle violence on our streets. We need the support of the local community here; I urge anyone who has information that could help investigators to approach officers at the scene, or call 101 immediately.
Anyone with information, video or images that could help police should call 101 or post @MetCC via X ref CAD 7417/2 Oct.
