A second man has been arrested on suspicion of murder following the death of rapper Lamar Jackson at a London Jubilee party.
The 33-year-old was arrested on Wednesday and has been bailed until July, Met Police said.
Police were called to reports of a stabbing following a party in Chigwell Rd, Woodford Green in the early hours of Friday June 3.
Emergency services found Mr Jackson, who performed under the stage name Hypo, suffering from stab injures.
Despite their best efforts, the 39-year-old died at the scene.
A post mortem examination confirmed the cause of his death was “sharp force trauma” to his chest.
On Monday a 32-year-old man was charged with murder and possession of a bladed article as part of the investigation.
He appeared at the Old Bailey on Wednesday where he was remanded in custody to reappear on August 24.
Detectives from the Met’s Specialist Crime Command are continuing to investigate Mr Jackson’s death.
They have urged any witnesses to come forward.
Hundreds of people were at the event as it ended and many would have seen what happened, police said.
“Lamar’s family are grieving and need your help. If you saw anything, or managed to record the incident, then please call us,” urged Detective Chief Inspector Laurence Smith.
"Lamar’s family are desperately trying to find out what happened and your phone call could help them understand why Lamar was taken from them - please call.”
