Police have now identified the victim of a fatal assault in Blyth as 30-year-old Scott Patterson.
Officers said they received a report that a man had been assaulted inside an address on Hallside Road in Blyth at 1.55am on Monday 19 August.
The victim had been socialising with people he knew inside the house when he got into an altercation and sustained serious injuries, believed to have been caused by a bladed article.
The North East Ambulance Service dispatched a rapid response team, a doubled-crewed ambulance and a clinical care manager to the scene while support was also provided from the Great North Air Ambulance. Paramedics arrived at the address but the man was pronounced dead at the scene.
Officers also attended but say they believe the person responsible, known to the victim and who had been in the address throughout the evening, had left the area.
Northumbria Police's Superintendent Helen Anderson, the senior investigating officer on the case is reassuring residents there is no wider risk to the public.
A post-mortem will take place later today to establish the cause of death.
