A 32-year-old woman is in a life-threatening condition in hospital after being stabbed at the Notting Hill carnival, the Metropolitan police have said. The force said on Sunday it was aware of three stabbings at the annual west London celebrations, with a 29-year-old man in hospital with non-life threatening injuries, and a 24-year-old man also stabbed whose condition had yet to be confirmed. Fifteen officers were assaulted, although none were seriously injured, and 90 arrests had been made on Sunday, police said. A force spokesperson said: “Hundreds of thousands of people came to Notting Hill carnival today to enjoy a fantastic celebration. Our officers have been on duty working to keep them safe as part of a very carefully planned policing operation. Regrettably, a minority came to commit crime and engage in violence.” Arrests were made for a range of alleged crimes including assault on an emergency worker, assault, possession with intent to supply, sexual offences and robbery, the police said. Suspects were also arrested for drugs possession, theft, possession of a nitrous oxide and public order offences. Earlier, the force said it had been granted greater search powers to prevent further violence after a man was stabbed and knives were recovered.
