A man has been charged with murder after two people were stabbed to death about a mile apart in the Camden area of north London on the same night last week.
Isaiah Popoola, 18, is due to appear at Highbury magistrates court later on Monday accused of the two murders, as well as grievous bodily harm and attempted grievous bodily harm in relation to two other stabbings on the same night.
Police found Abdikarim Hassan, 17, and Sadiq Aadam Mohamed, 20, dead last Tuesday night. Each had suffered stab wounds.
At about the same time two other men, aged 17 and 24, were also found with stab wounds, but police said neither had suffered life-threatening injuries. Their names have not been released.
Four other men, also unidentified, were arrested last Wednesday on suspicion of grievous bodily harm. Each has since been released under investigation.
Police put a section 60 notice in place after the attacks, giving officers powers of stop and search without suspicion.
