A three-year-old boy and 11-year-old girl are among four dead bodies found in a west London home.
Police were called just after 3.10pm on Friday (June 16) to concerns for the welfare of the occupants of a house in Staines Road, Bedfont.
Officers forced entry to the premises and tragically found the bodies of four people inside the house.
As well as a man and woman thought to be in their 30s, police also found an 11-year-old girl and a three year-old boy dead at the scene, Scotland Yard said.
All four are thought to be related.
Enquiries are under way in respect of formal identification and informing next of kin.
The Met's murder squad are investigating.
Chf Supt Sean Wilson, local policing commander in west London, 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.”
Enquiries continue.
Anyone with information that may assist the investigation is asked to call 101, quoting reference 5135/16Jun.
