A paedophile obsessed with children's knickers sent sick photos of a child to another pervert.
Scott Butler revealed his "depraved" sexual interests in chats with undercover police and an underage girl. The 33-year-old was then discovered to have taken indecent pictures of a girl and shared them online.
Liverpool Crown Court heard Butler blamed "stress" for his twisted behaviour, which he claimed was "escapism". But Judge Andrew Menary, QC, told him: "It's plain from all of the circumstances of this case that you have an unhealthy and inappropriate interest in sexual images of children, particularly in relation to children wearing knickers or soiled knickers."
