A man who was stabbed to death in London at the weekend has been named by police as Terrell Davis, the brother of US rapper 21 Savage.
The 27-year-old, who lived in Lambeth, was found injured by ambulance workers in Brixton Hill shortly before 6pm on Sunday, and was pronounced dead at the scene.
On Tuesday, 21 Savage shared a photo on Instagram and wrote: "Can't believe somebody took you baby bro I know I took my anger out on you I wish I could take that sh*t back."
Mr Davis and 21 Savage, real name Sha Yaa Bin Abraham-Joseph, who was reportedly born in London, are believed to be half-brothers.

The rapper is best known for hits including the Grammy-winning A Lot and chart-topper Rockstar with Post Malone. Last year, he was involved in an immigration row after being arrested in the US over accusations he had arrived from the UK in 2005 and overstayed his visa.
Police have said Mr Davis's family have been left "distraught" following his death.
A 21-year-old man was arrested on suspicion of murder in south London on Tuesday and remains in police custody.
Detective Inspector Chris Wood, from the Met Police, said: "An arrest has been made and we continue to follow a number of leads following this tragic loss of a young life.
"Terrell's family are distraught and we are providing them with support via specially trained officers as they begin to grieve for him."
DI Wood said officers had spoken to a number of people but "believe there are others who have yet to come forward and tell us what they know".
He continued: "The answer to what happened to Terrell lies somewhere in the community and there will be people with key information that could help us bring justice to Terrell's family.
"Police and communities must work together to combat violent crime. If you are concerned about telling us what you know, or would not usually interact with the police, I can assure you that anything you tell us would be in the strictest of confidence."
