There has been a massive drop in the number of Irish teens using the controversial web site ask.fm.

Despite a minimum age limit of 13 years, 85% of nine to 12-year-olds are using social networking website Facebook, causing principals and teachers to have to deal with cyberbullying on an almost daily basis.

Six out of 10 employees have been bullied at work but most are too frightened to report it, it has emerged.

Just one in 10 children tell their parents they have received threatening or abusive text messages.

A parent forced to take her son out of school for his own safety says cyber-bullying should be treated in the same way as if it happened in the school grounds.
