South African mother held after children's bodies found in London

A woman has been arrested on suspicion of murder after three children were found dead at a house in London, British police said on Wednesday.

Officers were called at about 9.30pm (2030 GMT) on Tuesday evening to the large house in New Malden, south of the capital, where they discovered the bodies of three young children, four-year old twin boys and their little three-year old sister.

"A 43-year-old woman  has been arrested on suspicion of murder and remains in custody at a south London police station," the Metropolitan Police said in a statement.

The couple who moved into the neighbourhood  a year ago are  believed to be from South Africa, and are known as Gary and Tania Clarence.

 The couple had four children of whom three were believed to have a 'life-limiting genetic disorder'.

Detectives are not looking for anyone else in connection with this incident at this time, the Mail Online reported.

Post mortem examinations will be carried out on the three children later today to establish the cause of their deaths.
