The X files were testimonies of people who claimed to have been victims of Dutroux. They had been created after judge Jean-Marc Connerotte had made a public appeal for victims to come forward. In total at least ten victims subsequently contacted the police. All of the witnesses were given the code name "X number". One of the witnesses' names, namely X1, was revealed to be Régina Louf. X1 said that from the age of 11/12 onwards a family friend named Tony Van den Bogaert took her to sex parties with the approval of her family. Several witnesses and family members of Louf confirmed that she had a sexual relationship with Van den Bogaert starting from at least age 12. However, Van den Bogaert has never been interrogated, charged or convicted for sexual abuse. She claimed that other minors were present at the sex parties and that those were secretly filmed for blackmail purposes. She said: ""It was highly organised. Big business. Blackmail. There was a lot of money involved."" During her testimony she described some regular clients including judges, a prominent politician and one banker. She gave the police names, addresses and detailed description of two murders that matched unsolved cases of the two murders of teenage girls. Louf said that the parties didn't only include sex but also sadism, torture and murder. She claimed that one of the organisers of the parties was a man she knew as Mich (Jean Michel Nihoul). Louf described him as a cruel man, who sadistically tortured girls.
