The investigation — named operation LATTISE — involved cops scouring more than 100,000 chat-room logs.

"Online child sexual abuse is a national threat," Police Scotland Assistant Chief Constable Malcolm Graham said in the statement. "The reality is it is happening now, not only in Scotland but across the world, to children of all ages, from infants to teenagers."

Police did not release the nationalities of the suspects or victims.

"Online child sexual abuse is not a victimless crime," Graham added. "Children, from toddlers to teenagers, are being sexually abused and exploited now in Scotland and when an image or video clip is shared or viewed, they are being re-victimized."
