A man has been charged in London with the murder of a pregnant woman and the manslaughter of her baby son, police said.

Kelly Mary Fauvrelle was eight months' pregnant when she was killed in the bedroom of her home in Thornton Heath, London, in the early hours of 29 June.

The 26-year-old's baby son, who was named Riley by family members after he was delivered by paramedics, died in hospital on 3 July.

Aaron McKenzie, 25, of Peckham Park Road, Peckham, was arrested on Thursday and taken to a central London police station.

Police said early today that he had also been charged with one count of possession of an offensive weapon.

The attack took place in Ms Fauvrelle's bedroom while her whole family was at home and relatives heard her screams at around 3.30am.

Two men had previously been arrested on suspicion of murder.

One, aged 37, was released with no further action, and a second, aged 29, has been released on bail until early August.

Mr McKenzie is due to appear in Camberwell Green Magistrates' Court tomorrow.
