Moment drill rapper who murdered 18-year-old following social media row brags about stabbing rivals 'on sight'

By RORY TINGLE, HOME AFFAIRS CORRESPONDENT Published: 00:10, 4 August 2026 | Updated: 00:10, 4 August 2026 This is the moment a drill rapper who murdered an 18-year-old after a social media row bragged about stabbing his rivals 'on sight'. Tayvon Etefia, 18, rode a high-powered electric dirt bike through Enfield, north London, before his passenger, Emmanuel Popoola, also 18, fatally shot Keanu Harker in the head and chest with a pistol on the evening of June 26 last year. The murder came against a backdrop of violence arising from a rivalry between two Enfield gangs: the Get Money Gang (GMG) and the 3x3 gang. This was sparked by social media posts claiming that Popoola, who, like Etefia, was affiliated with GMG, did not have enough money to buy mobile phone data. Six days before Keanu's murder, Etefia, under the moniker 'TakeRisks', rapped about attacking gang rivals and burning their clothes. His lyrics included the line 'Any green boy gets chinged [stabbed] on sight', which referred specifically to 3x3 members. Tracks by other GMG members referred to keeping a 'scoreboard' of kills and mocked Keanu's death. In one track, 007, the artist described riding a Sur-Ron e-bike while shooting a gun. At Etefia and Popoola's trial, prosecutors presented the lyrics as evidence of the ongoing gang war and how GMG members were going on 'glide-outs' with the intention of attacking rivals. The Metropolitan Police said the tactic helped convict both men of murder before they were jailed for minimum terms of 28 years each. But it will not be possible in future if a campaign succeeds in preventing drill rap lyrics from being presented as evidence in court.

But detectives and families of victims fear any prohibition will lead to dangerous offenders escaping punishment. They include Keanu's mother, Kristen Harker, who said the use of drill lyrics as evidence 'can help bring justice to victims and their families'. 'In Keanu's case, the drill music made by those involved and their gang became an important part of the evidence,' she said in a statement shared exclusively with the Daily Mail. 'It helped show the bigger picture and played a part in helping to achieve justice for my son. That is why I believe that when lyrics are genuinely linked to real crimes, they should be looked at alongside all the other evidence. 'Keanu's life mattered. He wasn't just a headline or someone's lyrics. He is my son, and he is loved more than words can ever say. 'I hope no other family has to go through the pain of hearing their loved one's death celebrated in a song. If music is being used to glorify real violence, it shouldn't be ignored. If it can help bring justice to victims and their families, then it should be taken seriously.' Ms Harker added: 'I'm not saying all drill music is bad. There are artists who use it to tell their stories without promoting violence. But some people use it to glorify gang culture, threaten others, and boast about real crimes. When that happens, it shouldn't just be brushed off as "just music".' In another case, a rap video filmed on a killer's mobile phone was used to secure justice for a murdered 15-year-old. Rene Graham was gunned down during a family 'fun-day' at Emslie Horniman's Pleasance Park, also known as 'Teletubbies Park', in the west London neighbourhood of Ladbroke Grove in July 2024. Etefia tried to flee to France but was hauled off the train at London St Pancras and arrested on the platform Popoola was hunted down by police, who used his girlfriend to track him to an apartment in the French capital Keanu was fatally shot in June last year after a row on Snapchat Chilling CCTV footage showed 25-year-old Aderahman Boumzough calmly approaching the busy park before he pulled out a handgun, walked through the children's play area and shot Rene in the chest. During the police investigation, Boumzough's phone was found to contain a video of him rapping about the firearm jamming. In the video, obtained by the Mail, he said: 'Don't you hate it when your ting jams? I was prepared to take a soul, but Allah had a different plan.' The fact that the killer's gun had jammed had not been made public at the time. As Boumzough had disguised himself with a balaclava and no DNA was found on the gun, the lyric provided important evidence that he was the killer. At present, police can produce lyrics or use a defendant's appearance in a music video as evidence that a suspect is affiliated with a gang or involved in a specific crime. But the Art Not Evidence group wants a change to the law that would limit the use of lyrics to cases where it can be said they are directly related to a crime, preventing police from using the music to prove gang affiliation. An open letter sent to the Government argues that 'these creative expressions have no connection to the serious crimes alleged and are used to paint a misleading and prejudicial picture, conflating art with evidence'. Signatories to the letter include rapper Giggs and DJ Semtex, senior academics from the universities of Oxford, Manchester and the London School of Economics, and Riel Karmy-Jones KC, chair of the Criminal Bar Association. Campaigners also want to see independent music expert witnesses instead of police witnesses in court. Baroness Shami Chakrabarti has said: 'We're in a ridiculous position at present where somebody's musical taste is somehow probative of their criminal intent. It is like saying that my love of Francis Ford Coppola's The Godfather makes me a mobster.' Aderahman Boumzough rapped about his gun 'jamming' after shooting dead Rene Graham As Boumzough (pictured) had disguised himself with a balaclava and no DNA was found on the gun, the lyric provided important evidence that he was the killer But the Met's lead on gang material, Detective Sergeant Matt Corbin, fears there could be 'incorrect verdicts' as a result. He said: 'It is a key tool in securing justice for victims and taking violent criminals off our streets. 'It has proved essential in proving cases of serious violence, including murders, by making sure juries have sufficient information to reach a verdict. 'To be clear, restricting officers' use of drill and rap lyrics as evidence could significantly limit our ability to prosecute cases of serious violence and secure justice for victims.' He told the Daily Mail: 'Our policy is very clear: we would treat opera, pop or anything else the same way if it was linked to a murder.' In some murder cases, drill artists 'are storyboarding everything they're going to do,' the officer added. Earlier this week, the mother of a 15-year-old boy whose killer wrote a rap about his murder said it was 'disgusting' that campaigners want to restrict the use of lyrics as evidence. Leonardo Reid was about to start his GCSEs when he was stabbed to death at a music video shoot in June 2023. He had no links to gangs but was excited to hear filming would take place outside his home in Archway, north London, and went to watch with his older brother. Leo's killers believed members of a rival gang would be at the shoot and ambushed it with machetes, killing him and Klevi Shekaj, 23. A day later, Xavier Poponne wrote a rap on his phone bragging about the attack, which led to him being convicted of murder. Rene Graham, pictured, was shot in the chest in front of families and children in a popular park  'Leo was a quirky little boy,' his mother, Valentina Locci, told the Daily Mail. 'Highly missed, highly loved. 'If you think it's acceptable as an artist to talk about someone who has been murdered, then we've got to be able to use that in court. 'If we can't, it shouldn't be allowed on any platform, YouTube or social media.' Ms Locci, who previously worked as a behaviour manager at her son's school, said it was 'heartbreaking' to read lyrics about the murder. 'They were such a crucial part of getting justice. So as much as it was painful, I was all for it.' On the proposed restrictions, she added: 'It's disgusting. 'Talking about that, about how you killed someone, will never be acceptable.' The case is one of many in which drill, a sub-genre of rap, has been central to a prosecution. In October, Lekan Akinsoji was jailed for 28 years for fatally stabbing a gang rival while wearing a balaclava, bragging later in a song that he would escape justice as 'no face, no case'.
