Two young men were shot dead and a third left fighting for life following a street gunfight in east London early on Tuesday.
Armed officers responded to the triple shooting in residential Henley Road, Ilford around 12.16am.
Paramedics called police after reports of a fight in progress and shots fired.
At the scene officers found three men, two in their 20s and one in his 30s, with gunshot injuries.
One of the victims was pronounced dead at the scene. Another man died a short time later.
Scotland Yard believe they know the identity of one of the deceased and are working to inform next of kin.
A police spokesman said: “The third victim aged in his 30s was taken to hospital, where he remains in a critical condition.
“At this early stage there have been no arrests. Enquiries into the circumstances are ongoing.
“Crime scenes and road closures are in place.”
The double murder is the fifth killing within a ten-mile radius of east London in six days.
