Detectives are continuing to appeal for witnesses and information following the launch of a murder investigation in Haringey.
Police were called at 05:51hrs on Sunday, 7 April to Northumberland Park N17, after a man was found unresponsive.
Officers responded with London Ambulance Service paramedics.
On arrival they found a man suffering from a number of stab injuries. CPR was administered but despite the best efforts of emergency services the man was pronounced dead at the scene.
Although formal identification has not taken place, officers believe him to be 46-year-old Okechukwu Iweha, who was from the local area.
His next of kin have now been informed and are being supported by specialist officers.
A post-mortem examination will be held at Haringey Mortuary later this week.
Detective Chief Inspector Neil John, from the Specialist Crime Command, is leading the investigation. He said: “I am urging anyone who saw or heard anything suspicious to please come forward and speak with us.
“We are working hard to build a timeframe to establish what has happened. Were you woken up by a disturbance, or did you see anyone running from the area? I would ask that you check any private CCTV or dash cam footage to see whether you captured anything that might assist us.
“Another family has been left grieving and we are doing everything we can to find answers to their questions and locate whoever is responsible for this murder.”
At this early stage there have been no arrests and enquiries continue.
Chief Superintendent Caroline Haines, in charge of policing in Haringey, said: “Our thoughts remain with the family family who are having to come to terms with his life being taken in such a violent way.
“I would like to reassure the local community that we are working around the clock to assist specialist detectives with their investigation.
“We are grateful to residents for their patience and understanding while we go about this crucial work. The crime scenes and forensic work will have caused disruption but it is imperative that we gather any evidence that might prove vital in leading to an arrest.
“If you have information that could help us, no matter how insignificant it may seem, please tell us. You will see officers on the cordons and on patrol and they will be ready to listen to you.”
