A 16-year-old has become the fifth person to be arrested in connection with a stabbing at Notting Hill Carnival.
Four men, who have already been arrested, are currently in custody at different police stations across the capital.
The victim suffered stab wounds to the stomach and hand and was rushed to a central London hospital on Monday evening. He is still said to be in a serious but stable condition.
The incident has tarnished an otherwise safe carnival in comparison to previous years. Following the riots that took place in London earlier this month, security was tight, with police making 40 pre-emptive arrests last week.
A record number of officers were patrolling the event, with special permission to stop and search individuals and get any person to remove items that concealed their identity.
Just under 500 people were treated by the London Ambulance service over the weekend, 59 of whom required hospital treatment. This was down on last year’s carnival, which saw 706 people receiving medical treatment and 117 going to hospital.
Police are still appealing to anyone who may have witnessed the attack or has any information that might assist them with their investigation.
