A British couple, who allegedly abused their son and daughter online while others watched, has been taken into custody after police smashed an international paedophile ring.
The two, who have not been named, were running an "open naturist" website for parents who also abused their children, the Daily Mail reported.
According to the Herald Sun, the pair was tracked down as part of Task Force Argos, an operation led by detectives in Queensland, Australia.
Further arrests included two fathers from Texas and Michigan, in the U.S., who were traced through the British couple's computers.
The men had allegedly used Skype to contact each other, and share images of abuse of their children.
Detectives were first alerted to the paedophile network after experts intercepted an email containing child pornography sent to a known Australian offender.
The investigation led them to other members of the network.
