A man has been arrested on suspicion of murder after a man was stabbed at a block of flats in north London.
Officers were called to Priestley House, Wembley, shortly after 10am on Saturday morning, but the victim in his 60s was pronounced dead at the scene.
A man, who had barricaded himself into an address and was Tasered by Metropolitan Police officers, was then arrested on suspicion of murder.
The suspect, 45, remains in custody and it is believed the two men knew each other.
Police were previously called to the same address shortly before 7am on Saturday to reports of a noise complaint and an activated smoke alarm.
Scotland Yard officers and the London Fire Brigade both attended, and a man was spoken to, the force said.
The Met's Directorate of Professional Standards has been informed of the incident because of the earlier call.
