A heavily pregnant woman who was stabbed to death has been named as Kelly Mary Fauvrelle.
Two men have been arrested on suspicion of murdering the 26-year-old, who was pronounced dead at a house in Croydon, south London, early on Saturday.
Her baby was delivered at the scene by paramedics and is in hospital in a critical condition.
Police said a 29-year-old was in custody and a 37-year-old had been released under investigation.
Both men were arrested on Saturday. Scotland Yard said it was keeping an “open mind as to motive”.
Det Ch Insp Mick Norman described it as “a horrific incident” and said the force’s “sympathies go out to [the woman’s] devastated family”.
“At the forefront of our inquiries is understanding what exactly has led to these tragic circumstances, and we are doing everything we can to establish the facts.”
