A 43-year-old woman has been arrested in connection with the death of three young children in New Malden.
Police were called to a home in Thetford Road shortly after 9pm last night following a 999 call.
The bodies of the children were found at the scene.
A police statement said: “A woman has been arrested and is being held at a police station in south London. Enquiries are continuing.”
Police have released no further details, but neighbours have told London Live’s James Banks that a young family moved into the property within the last six or nine months.
Neighbours have also said four children lived at the property, three had life limiting disabilities.
A police cordon remains around the scene as the investigation continues.
