Based on a tip-off from the International Criminal Police Organisation's (INTERPOL) Crime Against Children unit, the Brazilian Federal Police's Child Exploitation Unit (NURCOP) has arrested a fifty-year-old Brazilian for producing child sexual abuse material (CSAM) and managing a Portugese-language forum on the darknet. The offender had posted abusive pictures of minors in several darknet forums which had hundreds of thousands of registered users, and one of those forums is believed to be the largest Portuguese-language child sexual abuse forum on the darknet.
