Europol says it has arrested 115 alleged child sex offenders in raids across 18 EU nations and Canada, BBC reported.
It says its two-year Operation Typhoon - targeting child sex offenders on the internet - has now been concluded.
The suspects had different professional backgrounds, some of them being teachers or caretakers in close contact with children.
It says it identified five children - aged between four and 12 - who had been victims of sexual crimes.
