Knife crackdown hailed 'success'
Someone is arrested every 51 minutes in London as officers try to fight knife crime among young people, according to police figures.
Some 10,266 people have been arrested by the Metropolitan Police (Met) as part of Operation Blunt 2.
The project was launched after a surge in knife crime last year when 22 teenagers were stabbed to death.
More than 5,480 weapons, including machetes and hundreds of kitchen knives, were also seized by police.
Arrests were made as officers armed with metal detectors stopped and searched 287,898 people across London.
Acting Deputy Commissioner Tim Godwin said: "There are still far too many kids getting involved in what they would loosely classify as gangs.
"This means it is not job done - we have go to continue and keep the job going for another year, two years or however long it takes."
He added about nine out of 10 people caught with a knife are now charged.
The Met said they had noticed a reduction in knife violence in young people in the past year.
Of the eight teenagers killed in 2009, five have been attacked with knives.
Met figures from January to April this year show the number of knife offences dropped by 11.5% and the number of victims of youth violence fell by 10%.
