The victim, named on Sunday as 18-year-old Ghulam Sadiq, was attacked in Leytonstone, east London, on Saturday afternoon. Police were called to Leytonstone High Road at 2.15pm following reports of a stabbing. A worker at a pizzeria near the attack said officers fought to save him before he was pronounced dead at the scene. An investigation into the killing has now been launched and the Met is appealing for witnesses to come forward. Addullah Addullah of Massimo’s Pizza told the Express: “People gathered in the street, he (the victim) came to the door and said ‘uncle, help me’.” “He had stabbed himself very badly, no one could find the stab wound. “It was really scary when we saw the bleeding, it was bleeding badly. Officers attended and provided first aid until the arrival of the London Ambulance Service and the London Air Ambulance. The force has yet to make any arrests. Detective Chief Inspector Linda Bradley, from the Met’s Special Crime Squad, said: “Our heartfelt thoughts are with Ghulam’s family as they come to terms with this terrible tragedy, which no family should have to endure. “He was attacked at midday on the busy High Road on a summer Saturday afternoon. I know this will shock and horrify the local community and I want to assure them that we will do everything we can to identify and bring to justice those responsible. “The area is likely to have been busy at the time of the incident. I would like to appeal to anyone who saw anything worthwhile to come forward and speak to us. “Did you see the attack itself? Did you see a fight? Did you see someone acting unusual or in a way that made you suspicious? “Can you have dash cam footage from being in the area at the time? We want to hear from you. No piece of information is too trivial. “I would also like to thank the local businesses and residents affected by the road closures around the crime scene for their patience and co-operation during this vital initial phase of our investigation. We will work as thoroughly and efficiently as we can.” Anyone with information is asked to call police on 101, quoting 3896/06 AUG, visit the Major Incident Public Reporting website or call the independent charity Crimestoppers anonymously.
