A 16-year-old boy has been arrested on suspicion of murder after a woman was stabbed to death in Bermondsey on Christmas Eve.
Officers were called to a property on Spenlow House on Jamaica Road just after 10pm on Sunday to reports that a woman had been attacked with a knife.
A 22-year-old woman was found with knife injuries. She died at the scene despite the efforts of paramedics.
Her family have been informed.
A teenage boy, who is known to the victim, was arrested nearby on suspicion of murder and remains in police custody.
Chief Superintendent Seb Adjei-Addoh, local policing commander for Southwark, said: “This is a tragic incident and my thoughts are with the woman's family and friends at this incredibly difficult time.
“We recognise this will also have an impact on the wider community and we will have additional patrols in the area over the coming days to provide reassurance.”
Detective Chief Inspector Brian Howie added: “Our investigation continues and a team of detectives are working at pace to establish what happened that resulted in a young woman losing her life.
“My thoughts, and those of my team, are with her family and friends at this awful time.
"One person has been arrested, however we still need to hear from anyone who was in the Spenlow House area between 7pm and 11pm on Christmas Eve and may have seen or heard anything suspicious.
“I would urge anyone with any information that may be relevant to our investigation, no matter how insignificant it may have seemed at the time, to come forward immediately.”
A post-mortem will take place on Tuesday.
Anyone with information about the incident is asked to call 101 quoting CAD 5855/24Dec.
