A teenager who stabbed a policeman at this year's Notting Hill Carnival has been sentenced, according to police.

The 17-year-old, who cannot be named for legal reasons, had previously pleaded guilty to wounding and possession of knife with intent to cause threats and violence, the Met said.

Appearing at Wimbledon Youth Courts on Wednesday (September 23), he was given a six-month detention and training order for each offence, to run concurrently.

The youngster had been at the carnival with friends on August 31 when he became involved in a heated argument with a man on Elgin Avenue, police said.

A fight soon broke out which patrolling officers tried to break up. However, the defendant had drawn a knife and lashed out, stabbing one of the officers in his upper left arm. He was taken to hospital where he received stitches for the wound.

The suspect tried to drop the knife but other officers arrested him for grievous bodily harm. He initially denied responsibility but after members of the public said they had witnessed the incident, the 17-year-old was charged and subsequently entered guilty pleas.

Detective Superintendent Raffaele D’Orsi, of Kensington and Chelsea police, said: “This case demonstrates some of the dangers officers face when carrying out their duty. A simple argument in the street escalated and led to a police officer being stabbed. I am thankful that his injury was not life-threatening.

“Notting Hill Carnival is supposed to be a family-orientated, fun event. Attending armed with any weapon let alone a knife is unacceptable.

“Any person caught carrying such items will be brought to justice, this year 67 people were arrested for possession of weapons.

“The young man in this case has been swiftly brought before the court to answer for his actions. I hope that he, or any other young person considering carrying a weapon, reflects on the dire consequences of knife crime.”

The sentencing was delayed by one day after power cuts caused by heavy rain hit parts of Wimbledon on Tuesday (September 22).
