Seven years on from the murder of Tottenham teenager, Abdulkarim Boudiaf, police are offering a reward of up to £20,000 for information which results in the identificaiton, arrest and prosecution of those responsible for his death.
Abdulkarim, who was 18-years-old at the time of his death, was shot at Broadwater Road, N17 shortly before 22:30hrs on Saturday, 14 March 2009.
He was pronounced dead at the scene and the subsequent post-mortem examination gave the cause of death as a gunshot wound to the chest.
Despite the passage of time, Abdulkarim's murder remains unsolved and detectives continue to appeal for new information to bring the killer to justice.
Detective Chief Inspector Andy Chalmers of the Met's Homicide and Major Crime Command said: "I am hoping that someone who previously did not feel they could come forward will now, after seven years, feel able to provide us with the information we need to solve this case.
"On the evening of the murder, Abdulkarim was in the vicinity of the Elmhurst Public House with friends when, just before 10pm, he was confronted by his killer who shot him twice.
"Those responsible for this murder are still at large and today I am appealing for new witnesses to come forward. Your help could remove a dangerous killer from the community.
"Were you in or around The Elmhurst pub on the night of the murder? Did you see the shooting and who was responsible? Do you know who killed Abdulkarim?
"If you believe that you can help us to solve this murder, please get in touch with my incident room or Crimestoppers."
Anyone with information should call the Incident Room on 020 8358 0100 or call Crimestoppers anonymously on 0800 555 111.
