Two men have been arrested on suspicion of murder after a double killing in east London, the Metropolitan Police said.
A 20-year-old man was arrested in Ilford on Wednesday and a 21-year-old man was arrested in Northampton on Thursday.
They remain in custody at a south London police station.
Three men were found with gunshot injuries, Scotland Yard said.

Mr Mohamed died from hypovolemic shock after he suffered stab and gunshot wounds to the torso and Mr Sheikh died from stab wounds to the torso.
A 30-year-old man was taken to hospital with gunshot wounds and remains there in a serious but stable condition.
The families of all three men continue to be supported by specialist officers.
