A woman who was around eight months pregnant has been stabbed to death in south London.
Her baby survived and was delivered at the scene, but is now in a critical condition in hospital.
Police have named the woman who was murdered as 26-year-old Kelly Mary Fauvrelle.
Officers responded to reports of a woman in cardiac arrest in the Croydon area at around 3:30am on Saturday morning.
They discovered Ms Fauvrelle with stab wounds, and she passed away at the scene.
The child was delivered by ambulance personnel and taken to hospital.
Two men have been arrested in connection with the stabbing.
A 29-year-old man arrested on suspicion of murder remains in custody.
A 37-year-old man who was also arrested on Saturday has been released under investigation.
Detective Chief Inspector Mick Norman of the Met Police said: "This is a horrific incident in which a young mother has lost her life and her child is critically ill.
"Our sympathies go out to her devastated family; they are being supported by specially trained officers following this awful event, and I would ask that they are left alone at this time as they come to terms with the enormity of what has happened."
Police say they 'retain an open mind' regarding the motive for the killing.
