A woman stabbed at the Notting Hill carnival as she tried to stop a fight is in a coma in a life-threatening condition, a court has been told. Shakiel Thibou, 20, appeared at Westminster magistrates court on Wednesday charged with the attempted murder of Cher Maximen, 32. Maximen had been attending Notting Hill carnival with her three-year-old daughter and other family and friends on Sunday when she was stabbed in the groin shortly before 6pm, the court heard. She had intervened to try to stop a knife fight, the court was told. After the stabbing she had a cardiac arrest and remains in a life-threatening condition. She is in a coma after losing 20 units of blood; one of her lungs collapsed, while she may need to have a leg amputated, the court heard. Thibou is also charged with possessing a knife in a public place and violent disorder. He appeared in court alongside his two brothers, Sheldon Thibou, 24, and Shaeim Thibou, 21, who are both charged with violent disorder and assaulting an emergency worker. Sheldon faces an additional charge of possessing a stun gun. All three brothers wore grey tracksuits and spoke to confirm their names, dates of birth and addresses as they sat in the dock together at the hearing. Shakiel and Sheldon, from separate addresses in Hammersmith, west London, gave no indication of pleas. Shaeim, from Fulham, south-west London, indicated a not guilty plea. The district judge, John Zani, denied all three defendants bail and remanded them into custody to next appear together for a hearing at the Old Bailey on 25 September.
