This Morning presenters Holly Willoughby and Phillip Schofield broke down in tears as they learned how cyber-bullying drove a teenage girl to take her own life.

Nicola Harteveld, from Milford Haven, told the ITV programme how her daughter, 14-year-old Megan Evans, was told to hang herself in a last message she received before she died.

Willoughby was left speechless and Schofield was moved to tears as he said the story "got to all of us".

Ms Harteveld told the presenters her daughter was a bright, outgoing and popular teenager and none of her close friends or family noticed anything was wrong.

Speaking about the dangers of online bullying, she said: "Teach your children to be humble, and be kind.

"Words can't be taken back, and words can kill.

"Try and put yourself in that person's shoes."

Viewers took to Twitter to say more needs to be done in schools to prevent cyber-bullying.
