A third person has been charged with murdering an NHS worker, who was allegedly chased and stabbed eight times after he left his house to go shopping. Vagnei Colubali, 22, was charged on Saturday over the death of marketing graduate David Gomoh, 24, who was attacked outside his home in east London on 26 April while he was on the phone to his girlfriend. Colubali was also charged with conspiracy to cause grievous bodily harm with intent against another unidentified man whom he also allegedly threatened with a knife, Scotland Yard said. Colubali, who was arrested on Friday in Cambridge, was remanded in custody to appear before Thames magistrates court on Monday, the force added. Gomoh, who worked for the NHS in supplies and procurement and whose mother is a nurse, was killed just days before he was due to attend the funeral of his father, who died after contracting Covid-19. A postmortem examination gave the case of death as stab wounds to the chest and abdomen. Muhammad Jalloh, 18, of Stratford, Newham, and a 16-year-old boy, of Telford, Shropshire, appeared at the Old Bailey by videolink charged with his murder on 6 May. They are also accused of conspiracy to cause grievous bodily harm with intent in connection with another alleged incident shortly before Gomoh was found with knife wounds in Freemasons Road, in Newham. Judge Anthony Leonard QC set a plea hearing for 22 July and remanded the defendants into custody.
