A woman has died from stab wounds following an armed siege at a house.

Police said the woman in her 40s died at the scene of the stand-off in Cromwell Road, Peterborough, at about 06:40 BST.

A woman in her 30s, and a nine-year-old boy were taken to hospital, but police said their injuries were not thought to be life-threatening.

A man in his 40s has been arrested on suspicion of murder and taken to hospital with minor injuries.

Cambridgeshire Police sent armed officers who negotiated with a man inside the property before arresting him.

Earlier in the morning, a neighbour said she had seen a boy, aged "about nine" running in the street with blood on him.

A police spokesman said all three victims sustained stab wounds and all four involved were believed to be related.
