A woman remains in a critical condition in hospital after being stabbed at the Notting Hill Carnival, which she had been attending with her young child.
The force said the stabbing of the women, 32, was among three stabbings at the annual west London celebrations it was aware of on Sunday, 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.
