Detectives are appealing for more witnesses, after a waitress was stabbed to death while walking home in South Ealing.
Ania Jedrkowiak had finished work at a restaurant and was walking with a friend when she was attacked in an alleyway.
The 21-year-old was found by emergency services in Roberts Alley, off Church Gardens, with multiple stab wounds at 0.10am on May 17.
She tragically died at the scene.
Officers from the Met’s Specialist Crime Command are piecing together the events leading up to Ania’s death, and believe there may be several witnesses who have not yet come forward.
Det Ch Insp Brian Howie, senior investigating officer, said: “Ania’s life was taken in the most tragic of circumstances and her family are understandably completely devastated by what has happened.
“My team of detectives have already made significant progress, however I believe there may be people with information who we have not yet spoken to and I am keen to speak with them as soon as possible.”
Scotland Yard previously appealed for people who had been travelling or lived along South Ealing Road to get in touch if they saw anything unusual that evening.
Officers will return to the South Ealing tonight, May 23, to speak to people in the area and to offer reassurance.
The Met said there is nothing to suggest there is any risk to the wider community.
A post-mortem examination carried out on Thursday confirmed Ania died from multiple stab injuries.
Her family continue to be supported by specially trained officers.
Dennis Akpomedaye, 29, of Blewitt Street, Newport, Wales, has been charged with murder and is remanded in custody.
