A man is fighting for his life after being stabbed at Notting Hill carnival in west London.
A man believed to be in his 20s presented himself to an ambulance crew tent on Treverton Street, at the junction with Ladbroke Grove, after he suffered stab wounds at around 1pm on Monday.
The emergency services rushed him to a central London hospital, where he is being treated for life-threatening injuries.
Police have arrested three men, all aged 18, on suspicion of grievous bodily harm.
Among those detained, two of those were arrested on suspicion of possession of an offensive weapon, and the third was also arrested for possession of Class B drugs.

Around one million people are believed to have attended the two-day celebration of Caribbean culture, which is Europe's biggest street party.
Over the course of celebration, police have made over 150 arrests for assault, criminal damage, public order offences, possession of weapons, theft, sexual offences and drugs-related offences.
On Sunday, officers arrested 126 people, while another 28 had been taken off the streets by 3pm on Monday.
The detentions come after police officers carried out dawn raids last week in order to minimise disruption at the world-famous event.
