An 18-year-old man has been stabbed to death in the second fatal attack in London in five hours.
Police were called to a stabbing on the Brandon Estate in Camberwell, south London, at about 20:20 BST on Thursday.
Officers found a man with stab wounds and he was pronounced dead at the scene an hour later. No arrests have been made.
In a separate stabbing, a 15-year-old boy was killed near Stratford Shopping Centre shortly after 15:20.
Police believe he was either attacked on a bus, or shortly after getting off, and a second 15-year-old boy was also found with stab injuries which are not believed to be life-threatening.
The 18-year-old victim’s next of kin have been informed and a post-mortem examination is due to be held.
Scotland Yard has appealed for anyone with information to contact the force.
