The subsequent eight months of investigation has only resulted in four sentences according to police district reports sent to Norway's National Criminal Investigation Service (NCIS), NRK (Norwegian Broadcasting) reports.
The main delay is due to the enormous amount of confiscated material - video films, CD-ROMS and DVDs - that must be checked. The NCIS said that the material needs careful scrutiny, and that this has already led to information resulting in a new assailant being found.
Elisabeth Skogrand of Save the Children warns that speed may be of the essence for children being abused.
"We know from experience that some of these children live with sexual abuse today. It is extremely important that these children are identified as quickly as possible and rescue them from this abuse," Skogrand said.
Of the 275 cases, 197 were still under investigation in November and 56 had moved on to prosecution.
Fourteen cases were dropped after investigation confirmed that the computers confiscated contained material belonging to other users, and new cases were then begun against the true owners of the pornographic material.
