One, Nathan Eyre, spent two years carefully grooming his victim and putting him to work as a male prostitute before cashing in on his "investment."   He sold the 14-year-old to Raymond Hawthorne, the national leader of a British paedophile ring.

But the boy, who would drug himself to ease the pain of being abused by his "customers", was rescued after his mother reported him missing. Eyre, 38, of Leeds, latched on to the boy while he was still living at home, plying him with drink and drugs, alienating him from his family and brainwashing him into believing that what he was going through was somehow normal.
