The bodies of four people have been found dead at a flat in west London.
A man and woman in their 30s, an 11-year-old girl and a three-year-old boy were found in the flat.
Officers were called to the property on Staines Road, Bedfont, at around 3.12pm on Friday 16 June.
All four are thought to be related.
An investigation has been launched by the Metropolitan police.
Chief Superintendent Sean Wilson 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.”
