Kidnap of children by strangers is NOT Child Abduction

According to a definition of Child Abduction by the Norwegian Ministry of Justice and the Police Ministry of Foreign Affairs "A typical example of child abduction is when a parent removes a child from a country unlawfully, i.e. in contravention of the other parent’s custody rights. A child can also be retained abroad unlawfully following a lawful stay (e.g. for holiday or access purposes). The rules on child abduction and retention are identical, and the term child abduction is therefore used for both. In most cases, the child is abducted by one of the parents, although the same rules apply to abduction by grandparents or other relatives. Cases where a child is kidnapped by strangers, including where a ransom is demanded, do not constitute child abduction as defined here." The full text can be found here
