LONDON - A 42-year-old woman being questioned about the murder of three South African children is in fact their mother, British police confirmed on Wednesday.

Graphic designer Tania Clarence was arrested following a short stint in hospital for minor injuries.

Her husband, Gary, is expected to arrive back in London tonight from a visit to South Africa with their eldest daughter.

Last night, officers were called to their house in the southwest London suburb of New Malden where they discovered the bodies of the three-year-old twin boys, Ben and Max, and their four-year-old sister, Olivia.

Gary, a financier at Investec and a law graduate from Stellenbosch University, was informed of the deaths while in Cape Town.

The Clarence family moved into the house a few months ago, having left South Africa more than a decade before.

The three young children all suffered from "life-limiting genetic conditions," according to friends of the family.

The family home had recently been adapted to suit their mobility needs.

Neighbours, who've expressed shock at the news, say the children needed 24-hour care and that their mother was their main caretaker.

The family was described as a "wonderful unit" and as "lovely people".

It's not yet known how the children were killed but results of a post-mortem are expected to be released soon.

Police say they're not looking for anyone else in connection with the incident and are continuing to question the mother.

Flowers and teddy bears have been left outside the family home.
