Graham Norton has shared his personal experiences of knife crime as he made an appeal for people not to carry knives, saying "everyone is a victim in the end".
The presenter was stabbed as a drama student in London in 1989 and was also threatened with a knife a number of years later.
He told British newspaper The Daily Mirror that reports of knife crimes "don't trigger anything now" for him because they are so prevalent.
"I did have someone pull a knife on me again a few years after the first stabbing but there were people around and it was fine, it was outside a club," Norton recounted.
"Somebody wanted money and had a knife. And what's so sad about the knife crime now is that everyone is a victim in the end.
"Because people are losing their lives and equally the kids stabbing people, their life is destroyed for nothing, for this stupid thing because they couldn't get their heads around the consequences.
"In the moment it was, 'I want that phone' or 'You've got the keys to the car I want to steal'.
"I think it's a lack of imagination in the end, that if you had the empathy, that level of imagination to think it through, that the person you're stabbing could be a brother, friend, sister, mother or father, you wouldn't do it. Somehow people have been dehumanised."
When asked if knife crime was a "modern problem", Norton replied: "It's modern in that people have knives, not sure it's a modern problem.
"Young people are incredibly cruel to each other. Bullying has always been incredibly vicious.
"When you're young you don't understand what others are going through; you're so busy looking after yourself.
"I think young people can be quite cynical and brash and brutal; it's a modern malady but if you read Dickens, crime was horrific. It's more about economics than modern society.
"It's about people with nothing and if you've nothing to lose, that's a really scary place to be."
Norton is back on screens with a new series of The Graham Norton Show this weekend.
