A BBC Spotlight NI investigation has uncovered 731 photographs of Northern Irish schoolgirls on a pornographic website used by paedophiles.
The schoolgirls included pupils from 19 post-primary schools in Northern Ireland, including some of the best known grammar and high schools.
The schools covered a wide geographical area and all communities.
The photographs were those that girls had taken of themselves and their friends.
They were in normal situations, having fun both inside and outside school – pictures taken in innocence.
In some of the pictures underwear was exposed as well as some bare skin.
Neither the pupils, nor the schools, have done anything wrong.
The pictures appear to have been taken from legitimate social network profiles without their knowledge or consent.
