Police have launched a murder investigation after the death of a man found with stab injuries.

Metropolitan Police officers were called at 12.30am on Saturday to reports of a man who had been seriously injured in Staines Road, Hounslow, west London.

Officers attended along with London Ambulance Service and found a 31-year-old man with stab wounds.

Medics battled to save his life but he was pronounced dead at the scene.

The man’s family have been informed and are being supported by specialist officers.

Formal identification and a post-mortem examination have yet to take place.

No-one has been arrested and police are appealing for information.

The force has asked anyone who was in the area with information to come forward, including those who took photos, video, or dashcam footage at the time.

Detective Chief Inspector James Shirley said: “An urgent investigation is under way to establish what happened in the early hours of this morning and to identify who was responsible for this terrible attack.

“Our investigation will be extensive and painstaking, including a full forensic examination of the area, which is ongoing, and detailed inquiries to obtain all available CCTV.

“I am appealing for anyone who was in the area and has yet to speak with police to get in touch. Even if you do not believe you saw anything of particular significance, please make contact with detectives.

“I also want to hear from anyone who took photos or captured footage on their phone or other device, and from any drivers with dashcam footage from the local area at the time.”

Chief Inspector Karl Spour, of the Met’s West Area Basic Command Unit, said: “My thoughts are with the family and friends of the man who lost his life in this tragic incident.

“I know they will be given a great deal of support by Met officers as they try to come to terms with what has happened.

“Local people will see more officers in and around Staines Road and Hounslow town centre in the coming days.

“Our commitment to arresting and charging those who commit violent crime and further reducing the number of people killed or injured on our streets is total.”

Anyone with information or any witnesses yet to speak with police are asked to call 101, quoting reference 189/25jun, or Crimestoppers anonymously on 0800 555 111.
