A British man who used Facebook to share thousands of pictures of child sex abuse with other paedophiles around the world is now behind bars.
Ian Green, 45, was already a convicted sex offender.
He admitted distributing as many as 100,000 images of children through the social networking site.
On the day Green was jailed for four years, an ITV News investigation uncovered more disturbing pictures on Facebook - images that could be seen by anyone.
