Campaign to tackle cyber bullying aims to prevent suicides

Charities and campaigners are tackling cyber bullying as a BBC commissioned poll shows almost one in four children have suffered online abuse.

North West Tonight reporter Elaine Dunkley met Michelle Alker, whose 19-year-old daughter Caitlin was bullied online in the days before her death in August 2012.

She also speaks to Beat Bullying mentor Kate Dipper and Ged Flynn, of the Warrington-based Papyrus charity that helps prevent young suicide.
