The victims commissioner is visiting the Ben Kinsella Trust today to learn about its life-saving workshops, which educate young people about the horror of carrying knives.

The commissioner Baroness Lewlove and the Trust’s ceo Pat Green will also discuss how social media and violent music videos are “fuelling violence” on the streets of Islington and elsewhere around the capital.

The anti-knife crime charity honours 16-year-old Holloway schoolboy, Ben, who was tragically stabbed to death in 2008.

In June the Gazette revealed 27 people had been murdered with blades in the borough since Ben died 10 years earlier.

And so far this year four people have been killed in Islington, with the most recent being Ali Al Har, 25, who died from a leg wound in Tufnell Park last month.

Baroness Newlove said: “I’m calling on Youtube and Google to act responsibly by cracking down on gang violence and ban graphic videos that incite senseless stabbings, hatred and murder.

“I am disturbed that tech giants profits over the lives of youngsters, and the stakes are high when young lives are lost. It’s time we said enough is enough, and took action to stem the knife crime crisis blighting our cities and communities leaving devastated families.”

Patrick Green added: “The influence social media has over young people should not be underestimated. A young person’s online world is every bit as important to them as their real world.

“Not only do we need to ban content that glamorises a gang lifestyle, we also need educate and help young people to stop liking and sharing this content.”
