The head teacher of a Fife secondary school faces a lengthy jail sentence after admitting possession of nearly 4,000 graphic images and videos of children being sexually abused.
David Wilson, 48, was remanded in custody after he appeared at the High Court in Glasgow on Friday.
The court heard nearly 1,000 of the images he possessed showed babies and toddlers being abused. In many of the pictures, clear pain and distress was visible on the children's faces.
The 48-year-old former head of Auchmuty High was arrested as part of the ongoing investigation following on from the discovery of Scotland's worst paedophile ring.
On Thursday, ringleaders James Rennie and Neil Strachan were handed life sentences for a catalogue of child porn and abuse offences, as well as conspiring to abuse children.
Rennie will serve at least 13 years while Strachan will have to serve 16 years before he will be eligible for parole.
Strachan, 40, and Rennie, 38, were snared alongside six other men linked through online chat rooms following a major 18-month police investigation. The others had already been jailed for a total of 43 years.
Sentencing, Lord Bannatyne told Rennie: "You were, in my judgment, like a spider at the centre of this conspiracy, weaving an electronic web bringing to fruition this appalling crime."
Following the sentencing, police revealed that the web reached further than the eight men already jailed.
They said Operation Algebra had so far identified a further 80 individuals with possible connections to the child abuse network, 60 of whom had already been charged.
Among them were Wilson and a Lothians man also accused of hoarding child porn images.
