A fourth teenager has been charged with the murder of 19-year-old Andre Aderemi in South Croydon.

Ali Zahawy, 18, of Bramble Close, Shirley, will appear in custody at Croydon Magistrates' Court today.

Mr Aderemi was found with fatal knife wounds in Heather Way, on the Monks Hill estate, on Tuesday last week.

Three other men, all 19, have already been charged with his murder and were remanded in custody afer appearing at Camberwell Magistrates' Court on Saturday.

Jamall Longergan, of Woodcroft Road, Thornton Heath, Fabio Cela, of Fryston Avenue, Addiscombe, and  Rodney Mukasa, of Shirley, are all due to appear at the Old Bailey this morning.

Mr Aderemi lived in Monks Hill before his family moved to Chatham, Kent, earlier this year.

The former John Ruskin College and Oasis Academy Shirley Park pupil's death prompted an outpouring of grief on the estate, where bunches of flowers and dozens of messages have been left in tribute.

Friends have described the teenager - an aspiring rapper under the name Dee Rose - as a "funny, bright and talented guy".

During an emotional church service in Monks Hill on Wednesday Mr Aderemi’s family begged young people to “stop the warring” so "another mother and another family doesn't have to be grieving like we are today".

His mother said the family had moved away from the estate to "get him out of this environment".
