Police have made a second arrest after a pregnant woman was stabbed to death in south London on Saturday. Kellymary Fauvrelle, 26, who was eight months pregnant, has been named as the victim whose baby was saved after emergency services rushed to Raymead Avenue, Thornton Heath at 3.30am on Saturday. Police had arrested a 37-year-old male yesterday, who has now been released under investigation. This is while a 29-year-old man has now been arrested and has been taken to a south London police station - where he currently remains. The baby, who was delivered at the scene is still in a critical condition in hospital. Today forensic officers were pictured leaving the property and officers remained on the scene. Specialist investigators could be seen swabbing surfaces in an alleyway running along the side of the house while police officers guarded a cordon at the front of the property. A neighbour identified Kellymary Fauvrelle, 26, as the victim who was stabbed to death at Raymead Avenue, Thornton Heath in the early hours of Saturday morning An ultrasound image uploaded to the mother's Facebook page in February saying she had been expecting this summer An image from Kellymary Fauvrelle's Facebook profile taken in April last year Forensic officers were today pictured outside the property wearing blue suits and purple gloves, while officers also remained on the scene London Mayor Sadiq Khan tweeted: 'Violence against women has no place in our city, and horrific murders in the home like this show the scale of the problem we face.' Khan's tweet continued: 'My heart goes out to this innocent child, and to the mother they have so tragically lost.' A Scotland Yard statement said: 'Detectives investigating the murder of a pregnant woman in Croydon have made a second arrest and have named the victim as Kelly Mary Fauvrelle. 'A 29-year-old man was arrested on Saturday, June 29 on suspicion of murder. He was taken to a south London police station where he remains at this time. 'A 37-year-old male arrested that same day has been released under investigation pending further enquiries.' One neighbour told the Mail on Sunday he had heard the sound of police dogs rifling through the property in the early hours of the morning. He added: 'It was pretty loud, it woke us up. We heard screaming, and then we saw police and paramedics. Later on I saw another woman come out and just collapse on the street.' Ms Fauvrelle was a keen motorcyclist and shared an image of an ultrasound in February, saying 'looks like riding season is on hold for me this year.' On her Facebook bio she wrote: '4 wheels move the body...but... 2 wheels move the soul.' An officer stands outside the address as a police cordon was set up while forensics officers searched the property In March last year she passed her bus driving test 'with pretty much full marks' with Arriva London - who operate Transport for London's buses. One friend commented: 'The only way is UP, well done Kelly.' Shaun Bailey, the Conservative London mayoral candidate, tweeted: 'Please God let this child survive. Please let this baby's family come together to free it from this most heinous arrival to our world.' Detective Chief Inspector Mick Norman 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. The address on Saturday evening after the mother was killed in the early hours of the morning Officers were called to Raymead Avenue in Thornton Heath at 3.30am on Saturday after the pregnant woman was fatally stabbed Forensics bags outside the crime scene at Raymead Avenue, Thornton Heath The death of the 26-year-old mother marks London's 64th murder his year following the fatal stabbing of a teenager in Shepherd's Bush on Wednesday 'A large crime scene is in place, and is likely to be in place for some time.' The mother is the 64th murder victim this year in the blood-drenched capital. Yusuf Mohamed became London's 63rd murder victim of the year when he was stabbed to death in Shepherd's Bush on Wednesday - despite witnesses claiming he put his arms up to show the attackers he wasn't armed.

The US President tweeted, 'He is a national disgrace who is destroying the City of London!' This followed a statement from the mayor on June 15, saying he would not 'waste his time' with Trump after he wrote: 'LONDON needs a new mayor ASAP. Khan is a disaster - will only get worse!' The US President tweeted, 'London needs a new mayor ASAP,' as he warned things 'will only get worse,' with Khan at the helm Sadiq Khan dubbing Trump a 'fascist' before Air Force One had even taken off earlier this month ahead of the state visit (pictured: Khan's video addressing Trump directly prior to his state visit) Two teenagers were murdered within 12 minutes of each other, 12 miles apart in the capital on Friday June 14, while a man was stabbed to death the following Saturday - making three killings within just 24 hours. Jeremy Corbyn said it was 'absolutely awful to see @realDonaldTrump using the tragedy of people being murdered to attack the Mayor.' The Labour leader tweeted: '@SadiqKhan is rightly supporting the police to do their job while Katie Hopkins spreads hateful and divisive rhetoric. They seek to divide at a time we need to come together.'All rights reserved for this news site dailymail and under his responsibility
