One stabbed and 145 arrested on Monday

One person has been stabbed on the final day of the Notting Hill Carnival in west London, the Metropolitan Police has said.

The victim suffered non-life threatening injuries, police added.

Officers made 145 arrests on Monday – mostly for possessing an offensive weapon or drug offences. Sixteen people were held for assaulting emergency workers, four for sexual offences and one for having a firearm.

More than a million people were expected at Carnival on Monday, a majority of whom police said had come “to celebrate” with a “minority of people using it as an opportunity to commit crime, including violence”.

Thousands of officers were deployed to the annual street party, which the force said was a “challenging event to police with very dense crowds”.

Police had also seized 41 weapons other than firearms as of 19:00 BST on Monday. In total, police arrested 249 people over the past two days at Carnival. One man arrested was wanted for an attempted murder in Hackney in July.

Three people were also stabbed on Sunday, with one fatality “narrowly avoided”, police said. A woman who was stabbed while with her child remained in a critical condition on Monday morning, according to police.

Met Police Deputy Assistant Commissioner Ade Adelekan said that Carnival was supposed to be a “family day” but was “marred by unacceptable violence”.

“We are tired of saying the same words every year,” he said. “We are tired of telling families that their loved ones are seriously injured, or worse. We are tired of seeing crime scenes at Carnival.”

Measures had been taken to reduce crime and violence, including implementing an order that gives officers greater stop and search powers and another that allows police to order the removal of face coverings and arrest those who do not comply.

The Met said it had worked with event organisers for months to secure the event.

Police also partnered with the charity Safer Spaces to set up zones to provide a safe place for women and girls, as groping or sexual assaults often increase in dense crowds, it said.
