A 16-year-old boy has been accused of the murder of Munashe Charles Kutyauripo in Woodford, east London, on Saturday 9 January.
The 16-year-old, known as Charlie, was stabbed after celebrating a friend's birthday party at a social club at Ashton Playing Fields, in Woodford, northeast London, police said.
He was taken to Whipps Cross University Hospital but pronounced dead shortly after arrival. A post-mortem examination held on 11 January gave the cause of death as a stab wound to the chest.
Charlie was the first teenager to be fatally stabbed in London in 2016.
The youth charged with his murder, who cannot be named because of his age, will appear in custody at Willesden Youth Court on Wednesday.
Four other teenagers have been arrested in connection with the death.
Two suspects, both aged 17, were arrested on 16 January at separate addresses in east London. Both have since been bailed until late February pending further enquiries, police said.
On 19 January two men, both aged 18, were arrested on suspicion of murder. Both have since been bailed until early March.
