A murder investigation has been launched after a woman died following a street attack in Eastbourne.
The woman was found on the pavement in Chawbrook Road, near her home just before 11pm on 26 April after suffering a serious head injury.
She was taken to Eastbourne District General Hospital and then was transferred to Hurstwood Park Hospital in Haywards Heath the following day where she remained conscious and her condition was assessed as serious but not life-threatening.
However, on Monday (11 May), the woman's condition worsened and she died later that evening.
Detective Chief Inspector Mike Ashcroft from the Surrey and Sussex Major Crime Team, who have now taken over the investigation, said: "This is a tragic incident. At first the victim appeared to be making progress, but her condition suddenly worsened over last weekend.
"This has now become a murder investigation. We would like to hear from anyone who was in the Dudley Road, Chawbrook Road area on the late evening of Monday 26 April, and who saw anything suspicious, perhaps an argument, or a man walking away from the scene.
"If you can help in any way, please contact us via firstname.lastname@example.org or call 101, quoting Operation Oban. You can also call the independent charity Crimestoppers anonymously on 0800 555 111."
