Police were called at about 00:10hrs on Friday, 3 June to reports of a fight at a venue on Chigwell Road.
Officers and the London Ambulance Service attended and found a man, believed aged in his 30s, suffering from stab injuries. Despite the best efforts of the emergency services, he was pronounced dead at the scene.
Although we await formal identification, the deceased is believed to be 39-year-old Lamar Jackson of Hackney. Mr Jackson’s family have been informed and are being supported by specialist officers.
A post-mortem examination will be held in due course.
Detectives from the Specialist Crime Command are leading the investigation.
A crime scene remains in place.
No arrests have been made and enquiries into the circumstances are ongoing.
Anyone with information is asked to contact the incident room on 020 8345 3985 or via 101 quoting reference CAD 66/03Jun.
Detective Chief Inspector Laurence Smith said: “This attack happened at a party and we know that a large number of people would have been in attendance. I would urge anyone who is yet to speak with us to come forward and let us know what you saw.
“It is possible that events leading up to the stabbing, and perhaps the murder itself, were captured on people’s phones. Please take a look and call us. It is vital that we establish what happened.”
An open bladed Lock-knife was later found dumped adjacent to the main crime scene and was forensically recovered by police.
It has not yet been established if it has any connection to the on-going incident.
