Met Police have launched an investigation after the bodies of four people, including two children, were found at a flat in west London.

Officers were called just after 3pm on Friday over concerns for the welfare of the occupants of a property in Hounslow.

After forcing their way in they discovered the bodies of a man and woman in their 30s, an 11-year-old girl and a three year-old boy. No one else is being sought in connection with the incident.

All four are thought to be related, although police are now formally identifying the bodies and informing their next of kin.

The investigation is being led by homicide detectives from Specialist Crime.

Chief Superintendent Sean Wilson, the local policing commander, said: “Our investigation is at a very early stage, and based on our initial enquiries, we are not currently seeking anybody else in connection with the incident.

“I know the shock and distress that this terrible incident will cause among the community in Hounslow and beyond. I can assure local people that specialist officers are working to establish exactly what happened and I will provide further information as soon as I can.

“I am also aware that this incident will be particularly upsetting for children, and I ask people to please be responsible about what they post on social media, including not naming or speculating as to the names of those who’ve died.

“There will be additional police officers in the area across the weekend, I urge anyone with information or concerns to speak with those officers.”
