An 18-year-old man handed himself into police today, Tuesday 6 December and was arrested on suspicion of murder. He remains in custody at this stage. Officers still need to trace another man whose image has also been released. Detective Inspector Laura Semple, Specialist Crime, said: “Do you know who this person is? He was caught on CCTV at the Carnival and we still urgently need to trace him. “If can you help or have any information – no matter how small – about Takayo’s murder please come forward.” Takayo, aged 21, sadly died in hospital after being stabbed at around 8pm on Monday, 29 August in Ladbroke Grove, under the Westway flyover. The rapper from Bristol had visited the Carnival with his sister and friends. A post-mortem examination showed he died from a stab wound to the right groin femoral artery. There were several hundred people in the immediate area surrounding the murder and probably many witnesses. Detectives are still keen to hear from anyone with information, including anyone who was filming or photographing in the area at the time and may have captured relevant footage or images.
