According to the lawsuit, the child pornographic material consists of 434 images and 472 films.
Half of the material at the man's disposal is considered to be particularly ruthless material.
The crime should be considered serious as the possession partly refers to material where the children are particularly young and are subjected to coercion.
The pictures and films constitute documentation of real abuse, the prosecutor writes in his lawsuit, which was submitted to Halmstad District Court on Wednesday.
In interrogation with the 24-year-old, he denies the crime.
