Deshaun was given treatment but despite the best efforts of medics, sadly died in hospital a short time later.
His family have been informed and they continue to be supported by specialist officers.
On Friday, a 15-year-old boy was arrested on suspicion of murder. Four days later, on Tuesday, a 14-year-old boy was also arrested on suspicion of murder.
Both were taken to an east London police station and were later bailed to return on a date in mid-October.Three people previously arrested on suspicion of murder - a 15-year-old boy, and two 14-year-old boys - have also been released on bail, as has a 34-year-old woman who was arrested on suspicion of assisting an offender.
Detective Chief Inspector Joanna Yorke, of the Met’s Specialist Crime Command, said: “Despite these arrests we are still very keen to hear from anyone who has information or footage relating to this incident.
“We are working hard to piece together a timeline of events that led to Deshaun’s murder and I urge anyone who saw something, or captured footage, to get in touch without delay.
“Deshaun’s devastated loved ones are asking why this happened – if you have information please get in touch and help us to give them the answers they so desperately need.”
