A teenager stabbed to death after being chased down Oxford Street during a mass brawl has been named as Jeremy Menesses, 17, from south London. Metropolitan police officers were called at 5.38pm on Saturday to reports of an assault on Market Place close to the West End shopping street and found the victim with a stab wound. He was taken to hospital for treatment, but was pronounced dead at 7.30pm. Three men, all aged 18 and who attended a south London hospital with stab injuries, were arrested on suspicion of murder, police said. All remain in custody and two have also been held on suspicion of assisting an offender. According to the Sunday Times, an attacker was seen chasing Menesses with a machete along the road before stabbing him. A bystander told the newspaper: “Someone was running down the middle of Oxford Street in broad daylight on a Saturday with a machete, chasing someone.” Det Ch Insp Katherine Goodwin, who is leading the inquiry, said: “This attack took place following a fight between a number of males in broad daylight and was witnessed by a large number of horrified onlookers. “We have spoken to a number of people already but need anyone who has information, video or images to speak to us and tell us what they know. Your assistance could prove vital as we investigate this terrible incident.” An increased police presence remains in the Oxford Street area following the incident, which Supt Rob Shepherd of the Central West basic crime unit described as shocking. “We are doing everything we can to support our specialist crime colleagues as they continue their investigation and urge anyone with information to approach officers on the street if they have information that they would like to share with us,” he said.
