Twenty-four young lives were cut short in London in 2017 in senseless and violent attacks.
Families have been left broken, without their sons, brothers, cousins, nephews, grandsons and friends following needless stabbings and shootings on the capital's streets.
Following a dramatic increase in knife-crime incidents - 12,074 from April 2016 to April 2017 compared to 9,752 in the same period in 2015-16 - Mayor Sadiq Khan launched the London Needs You Alive campaign in November.
At the campaign's launch, Mr Khan said: "London is the best city in the world, full of opportunity and one of the safest, but too many of our young people are being senselessly lost to knife crime - it has to stop."
"We can't solve the problem by police enforcement alone, we need to get the message across that our young Londoners are too valuable to risk their lives by carrying a knife," he said.
"They are our future musicians, artists, sportsmen and women, comedians, scientists, entrepreneurs and role models - we need them."
Weapon sweeps, stop and search and specialist operations targeting those who carry knives, plus moped crime, resulted in 900 arrests across the 32 London boroughs in November and December 2017.
Up until November 15, 40 Londoners under the age of 25 lost their lives due to knife crime in 2017.
A shocking 24 of them were aged 19 and under and were all male - the youngest victim was just 14 years old, his life had barely begun.
Eighteen of those below were stabbed, five were shot and one died from multiple injuries.
