International police led by a UK team say they shut down the largest internet paedophile ring yet discovered.
The global forum had 70,000 followers at its height, leading to 4,000 intelligence reports being sent to police across 30 countries.
The operation has so far identified 670 suspects and 230 abused children.
Detectives say 184 people have been arrested – 121 of them were in the UK. Some 60 children have been protected in the UK.
The three-year investigation, Operation Rescue, was led by investigators from the UK’s Child Exploitation and Online Protection Centre (Ceop).
