Gavin Walker reports on how the eight men were brought to justice
Eight members of a paedophile network have been found guilty of a catalogue of charges relating to child abuse and indecent images of children.
Neil Strachan, 41, was found guilty of the attempted rape of an 18-month-old boy and James Rennie, 38, guilty of sexually assaulting a three-month-old.
The Edinburgh men, and three others, were also found guilty of conspiring to get access to children to abuse them.
All eight men will be sentenced at a later date.
Colin Slaven, 23, also from Edinburgh, Neil Campbell, 46, John Milligan, 40, and John Murphy, 44 - all from Glasgow - Ross Webber, 27, from North Berwick in East Lothian, and Craig Boath, 24, from Dundee, were convicted of various charges.
All of those involved in the investigation and prosecution of the case have been profoundly affected by it
The family of Child F said: "For a year and four months now we have had to live with the impact and haunting consequences this has had on our lives.
"For over 15 years James Rennie seemed the closest of family friends, and it is hard to put into words the extent of the betrayal he has exacted upon us, as many of the details may identify our family and son.
"To subsequently learn that he abused our son, and invited others to do the same, has been devastating."
Speaking after the verdict, Morag McLaughlin, area procurator fiscal for Lothian and Borders, said: "Tens of thousands of photographic and video images of children being sexually abused were recovered.
"All of those involved in the investigation and prosecution of the case have been profoundly affected by it."

Det Supt Allan Jones, of Lothian and Borders Police, said: "It is every parent's nightmare that their children have been abused and they knew nothing about it.
"Despite that, the families have been a source of unwavering support throughout this investigation and it is our sincere hope the children will flourish and they will be able to enjoy the normal family lives they rightly deserve.
"What everyone must remember is that behind every image is a child who is being abused - it is definitely not the victimless crime some would like to portray it as."
The Operation Algebra police investigation to track down the men has uncovered dozens more suspects around the country and worldwide, many of whom have already been charged.
