The bodies of three children have been found at a home in south-west London.

A 43-year-old woman's been arrested after police were called to a house in New Malden last night.

She's being held at a police station in Surrey.

Detectives aren't saying how the children died.

Locals say the family had only recently moved into the area.  All three of the children had disabilities, described as life limiting genetic conditions.
