Dutch investigation journalists from "Argos" (NPO Radio 1) collected the experiences and stories of over two hundred victims of organized sexual abuse. A hundred and forty victims told Argos about ritual abuse. Six well-known people were mentioned as perpetrators by multiple participants in the investigation, and over ten abuse locations. A warehouse in the Bollenstreek was marked as a location for 'storage' and the production of child pornography. During the investigation the "Argos" journalists received an anonymous email stating the journalists had to 'beaware' because 'they know about your investigation', remarking ‘they’re going to get rid of evidence - just like they did with Dutroux’. The same day as the journalists received the e-mail, the warehouse in the Bollenstreek burnt down. According to Argos, the damage had been classified so severe by the fire department, that a cause of fire could not be determined.
