A dangerous paedophile at the centre of an international child sex abuse ring has been jailed indefinitely and told he must serve a minimum of six years. Gareth Hulme, 25, from Manchester, twice raped a ten-year-old after gaining the trust of the boy's parents and luring him away to walk his dog in woods. Hulme, described in court as a predatory paedophile who is "every parent's nightmare", attacked the lad at a summer festival in Cheshire last year - taking a photo on his mobile phone as he raped his victim. Hulme, a security guard, also lurked in internet chatrooms to groom other victims, including a 15-year-old boy, and was also attempting to arrange a meeting with a friend to have sex with a nine-year-old. When police raided his house following his arrest last June they discovered a hoard of sickening child porn on his mobile phone and computer. The discovery led to the unravelling of a child sex network and 23 other police forces, including Interpol, launched raids to arrest suspects as far afield as Ireland, Spain and Luxembourg. So far 25 people have been arrested since Hulme was held and Greater Manchester Police also traced other potential child sex offenders, three of whom were charged, including a former high school maths teacher.
