Emma-Jane Cross, CEO and founder of the charity BeatBullying, said many young people are suffering in silence from online bullying.
Bullying both on and off-line continues to be a serious problem for a huge number of teenagers and we cannot ignore its often devastating and tragic effects.
We work with hundreds of young people being cyber-bullied or trolled so badly that it can lead to depression, truancy, self-harm, or even force them to contemplate or attempt suicide.
