The NSPCC said the death of 17-year-old Daniel Perry appears to be "the first time we have really seen extortion happening, via the internet, of a young person".
NSPCC policy analyst Claire Lilley continued: "Children and young people love the internet to learn, explore and connect with people like them all over the world.
"But it's about teaching them that not everyone is who they say they are and teaching them how to respect one another in terms of their behaviour online."
