A murder investigation has been launched after a 26-year-old woman was found dead at a home in Feltham, west London.

Officers visited an address in Chertsey Road on the afternoon of Wednesday, 4 November, to carry out a welfare check. The woman was found at the property and pronounced dead, the Metropolitan Police said.

Her next of kin have been informed and are being supported by specialist officers. A post-mortem examination will take place in due course, as will formal identification of the woman.

Shortly after the discovery, a 31-year-old man was arrested on suspicion of murder. He was taken to hospital for treatment, where he remains under observation.

Detective Chief Inspector Sarah Lee, who is leading the investigation, said the force’s thoughts remained with the victim’s family at what she called a painful time.

“We understand an incident of this nature will cause concern for the community,” she said. “I’d like to reassure them that we believe this to be an isolated incident, and our officers acted quickly to detain a suspect.”

Detectives are appealing for anyone with information to come forward, particularly people with doorbell camera or dashcam footage from the Chertsey Road area around the time of the incident.

Anyone with information is asked to contact police on 101, quoting reference 01/8264940/26. Information can also be shared anonymously through the independent charity Crimestoppers on 0800 555 111.

Chertsey Road is in Feltham, in the London Borough of Hounslow, and the Metropolitan Police issued its statement on the case under a Hounslow heading. The address was visited by officers after concern was raised about the woman’s welfare, prompting the check that led to the discovery.

The investigation is at an early stage. A post-mortem examination will be carried out to establish the cause of death, and formal identification of the woman will also take place. Detectives are continuing their enquiries into the circumstances surrounding her death.

Police have stressed that they believe the incident to be isolated and that a suspect was detained quickly. They are keen to hear from anyone who was in the Chertsey Road area on Wednesday afternoon, or who has doorbell or dashcam footage that could help establish what happened.

Hounslow Council’s leader has also issued a statement following the launch of the murder investigation, as the local authority and police continue to work together in the area.

The investigation is being led by detectives from the Metropolitan Police, and enquiries into the circumstances of the woman’s death are continuing.
