A woman has been arrested on suspicion of murder after three young children were found dead at a house in southwest London in the UK.
Officers discovered the bodies when they were called to a large, semi-detached home in Thetford Road, New Malden, at around 9:30pm on Tuesday.
Sources say the three children - a girl (4) and two 3-year-old boys - were disabled and had "life-limiting genetic conditions".
The woman (43) was arrested and taken to hospital with minor injuries but later discharged. She is in custody at a south London police station.
A spokesman for the London Metropolitan Police said "We are not looking for anyone else in connection with this incident".
Reporter Joe Tidy, at the scene, said a South African couple - named locally as Gary and Tania Clarence - moved into the house with their four children around six months ago.
They moved in after the stg£1.2 (€1.45) million property was redeveloped with mobility equipment, including a lift. It is believed Mr. Clarence and the eldest child, who is around 7-years-old, are abroad, and are travelling back today.
'They were very friendly'
Tidy said officers removed evidence bags from the property this morning. It is unclear whether the children's bodies are still inside the house.
Post-mortem examinations are to take place later.
Neighbours said Mr. Clarence works in London city and Mrs. Clarence is a full-time carer for her children. One local, who did not want to be named, said she met the couple at a barbecue two weeks ago.
"They were very friendly. He played golf and he had been playing golf that morning. He was going to America for a golf championship, to watch" she said.
"We were out last night dancing and when we came home there were police cars and ambulances outside".
Retired nurse and health visitor Joy Devis (86) said she had been in the house "once or twice".
"They are a delightful couple, they seemed to be very happy" she said. "Their children were super, lovely children. They were very happy, there was a very nice atmosphere there".
She said the family had help from a nanny and a maid.
