Detectives investigating the fatal stabbing of 16-year-old John Ogunjobi in Tulse Hill are renewing appeals for assistance in finding those responsible for his death.
A reward of up to £20,000 is available for information that leads to the arrest and conviction of the person or people responsible for the murder.
Officers are also asking anyone who may have seen a black Audi Q5 in or around the Tulse Hill area at the time of the incident to come forward and speak to police.
Police were called to Greenleaf Close, Tulse Hill at 22.53hrs on 5 November 2018.
Officers attended along with the London Ambulance Service (LAS) and found 16-year-old John Ogunjobi collapsed in the street with stab injuries. Despite the efforts of paramedics, he was pronounced dead at the scene at 23:41hrs.
A post-mortem examination at Greenwich Mortuary gave cause of death as a stab wound.
An investigation is underway by detectives from the Homicide and Major Crime Command, led by Detective Chief Inspector Richard Vandenbergh.
DCI Vandenbergh said : “I am appealing to anyone who has information that could assist this investigation to come forward and speak to police. We believe the victim was attacked by a number of suspects and the altercation would have undoubtedly been witnessed by a number of people. We are also asking people to think back as to whether they saw a black Audi Q5 on the evening of the murder or in the days leading up to or following it. I hope that the reward associated with this case will help encourage people who have information, to share what they know. We are still working to establish the circumstances around the attack but believe that several people will have key information that would enable us to get justice for John’s family.
“Moreover, I think it is quite likely that some people who were friends with John will hold vital information that they haven’t shared with police. They should think about his death at such a tragically young age, think about the misery caused to John’s family and maybe think about the reward too – and then make what is surely an easy decision – to come forward and speak with police.
Anyone with information is asked to contact the incident room on 020 8721 4961 or call Crimestoppers anonymously on 0800 555 111.
Meanwhile, four men – aged 22, 20, 21 and 23 – were arrested on suspicion of murder and taken to custody at south London police stations. All four men have been released under investigation.
