The boy was found with stab wounds in Monmouth Road
A teenager suffered several knife wounds when he was stabbed at the Notting Hill Carnival in London.
The 15-year-old boy was found in Monmouth Road, off Westbourne Grove, by police at 1920 BST on Monday.
He had been stabbed in the leg, chest and abdomen and remains in hospital in a serious but stable condition. No-one has been arrested over the stabbing.
About 720,000 people attended the two-day carnival in west London, during which police made 222 arrests.
Most people were arrested for public order and drugs offences, al though there were 58 fewer arrests than last year.
Metropolitan Police Ch Insp Jo Edwards said the lower number of arrests was due to stop-and-search techniques implemented by police.
During a stop-and-search police also recovered a bulletproof vest and a knife from a group.
Despite fewer arrests, Kensington and Chelsea Council cancelled a surprise appearance by Ms Dynamite at Powis Square, hours before her event at the carnival, because of crowd safety fears.
A total of 741 people were treated by London's Ambulance Service at the carnival.
Police said the majority of these required treatment on Monday for heat-related illness.
