Mother held as 3 children with genetic disorders found dead

A woman is being held by police on suspicion of murder after three young children were found dead at a house.

The 42-year-old is suspected of killing a 4-year-old girl and twin boys, aged 3, who are all said to have suffered from a life-limiting genetic condition.

It is understood the three children were cared for full-time by their mother Tania Clarence, while their father Gary worked as a director at Investec bank. He is currently travelling back to England from South Africa.
