A new campaign's getting underway to challenge negative images of young Londoners and celebrate the contribution they make to our city.
The 99 per cent campaign is named after the fact that less than 1 per cent of young people are involved in committing serious youth violence.
It's being backed by actress Brooke Kinsella who's brother Ben was stabbed to death in Holloway in 2008, she's also the Government's knife crime advisor.
The campaign was started after a survey found half of people in London feel unsafe when teenagers are out on the streets.
