Homophile: A grooming music teacher who preyed on young boys was told today he would serve a minimum of five years in jail.
Andrew Kingsley, 23, also faces a lifelong restriction order after admitting a 'predatory campaign' of sexual abuse against children as young as 12 between 2007 and 2009.
At the High Court in Edinburgh, Kingsley, of Alloa, Clackmannanshire, was jailed for at least five years after pleading guilty last year to 31 charges, including using internet chatrooms to groom under-age boys for sex.
Judge Lord Pentland said the worst aspect of Kingsley's 'sustained criminality' was the 'devious manipulation and relentless pursuit' of his victims for his own gratification.
Lord Pentland told Kingsley the lifelong restriction order meant he would be subject to risk assessment and close supervision for the rest of his life.
He said: 'The intensity of your offending, its duration and the level of planning and calculation involved all support this view.
'In my opinion, if you are at liberty there is likelihood that you will seriously endanger the wellbeing of members of the public at large.'
Sixteen boys were targeted by Kingsley, who he begged for sex over the internet.
He committed serious sexual crimes against at least one young boy.
