The baby son of a heavily pregnant woman who was stabbed to death in south London has died.
Kelly Mary Fauvrelle, 26, who was eight months pregnant, died at a house in Raymead Avenue, Croydon, on Saturday.
Her baby was delivered by paramedics at the scene and was initially taken to hospital in a critical condition but died in the early hours of Wednesday, the Metropolitan Police said.
The boy had been named Riley by Ms Fauvrelle’s family.
The news comes as Scotland Yard released footage of a man seen running away from the house where she was found dead.
The CCTV shows a figure walking towards Ms Fauvrelle’s home at about 03:15 BST on Saturday, then running away 10 minutes later.
Ms Fauvrelle died at the scene but her baby was delivered by paramedics.
The Met said it was an “extremely challenging investigation”.
Det Ch Insp Mick Norman said officers “need to identify the man shown in the footage urgently, even if only to eliminate him from our inquiries”.
Police had been called to the address in Raymead Avenue, Thornton Heath, over reports of a woman in cardiac arrest.
Paramedics tried to save Ms Fauvrelle but she died at the scene.
Det Ch Insp Norman said he was aware of “speculation about whether Kelly’s attacker was known to her” but said police “are not in a position to say and we must retain an open mind”.
Two men have been arrested on suspicion of murder.
A 37-year-old man has been released with no further action while a 29-year-old man was bailed until a date in August.
