Notting Hill Carnival: Woman fighting for life after three people stabbed

The force said they made 90 arrests at the west London festival and "15 officers have been assaulted".

Officers say the alleged crimes include assault on an emergency worker, assault, possession with intent to supply, sexual offences and robbery.

It comes as 7,000 Met officers have been deployed for the two-day event which expects to see more than a million people attend.

On Sunday night a Met spokesman said: "Hundreds of thousands of people came to Notting Hill Carnival today to enjoy a fantastic celebration.

"Our officers have been on duty working to keep them sae as part of a very carefully planned policing operation.

"Regrettably, a minority came to commit crime and engage in violence."

LATEST DEVELOPMENTS:

• Notting Hill Carnival is 'ultimate example of two-tier policing', says ex-Scotland Yard detective
• Met reveals Notting Hill Carnival plan as police gear up for weekend of crime
• 'Compare this to Saint George's Day!' Alex Armstrong FUMES after police spotted dancing on Pakistan Independence Day

A section 60 order, which grants greater search powers to prevent further violence, will remain in place until 2am tomorrow.

The order also gives officers the power to demand the removal of face coverings being used to conceal a person’s identity - anyone refusing can be arrested.

Ahead of the event, the Met described it as a day in London’s cultural calendar that was also a "challenging event to police with very dense crowds and a regrettable history of a minority of people using it as an opportunity to commit crime, including violence".

The Met’s spokesperson for this year’s carnival, Commander Charmain Brenyah said she has "happy memories of the music, costumes, floats and fantastic atmosphere".

"Sadly, however, we know that for a minority of people, carnival is an opportunity to commit crime or to seek out violent confrontation.

"As a police officer on duty in previous years I’ve seen both the carnival I experienced in my youth, but also the other side of the same event when, later in the day, the atmosphere changes in some parts, with floats and costumes giving way to serious violence."

Over the past two years, one person was killed, 14 others have been stabbed and more than 125 police officers have been assaulted at Notting Hill Carnival.
