A 44-year-old man has been arrested on suspicion of murder after a 46-year-old woman was found fatally stabbed inside a house following a gas explosion in Stoke Newington, north-east London, the Metropolitan Police said.
Six fire engines and 40 firefighters were called to the scene on Dumont Road in Stoke Newington shortly before 5am on Tuesday.
Metropolitan Police and London Fire Brigade (LFB) are investigating the cause but the force has confirmed it is now being treated as a murder investigation.
LFB station commander Darren McTernan said: “Motorists and pedestrians are advised to avoid the area for most of this morning while investigations into the cause of this incident are carried out.”
“There are road closures in place on Stoke Newington Church Street from the junction of the A10 to Defoe Road. Residents should also note that Kersley Road is completely shut at this time.”
Crews from Stoke Newington, Islington, Homerton and Holloway fire stations were called to the scene.
