Police have released CCTV footage of two people they want to talk to after a teenager was stabbed to death on the street on Sunday night.
Paramedics called the police to Walthamstow High Street at around 11.30pm, where they found a teenage boy suffering from a serious stab injury. He was taken to a nearby hospital but died a short while later.
Though the victim has not been formally identified he is believed to be 17 year old Elijah Dornelly.
Officers described the attack as 'targeted' and say they believe the suspects had been waiting for Elijah and his friend.
Police want anyone who recognises the people in the video to call the incident room on 020 8358 0400, or contact police via 101, or tweet @MetCC.
