Twenty men have been arrested in an inquiry into a paedophile network in Norway, in the country's largest abuse case to date.
Many of the suspects are highly educated and include lawyers and politicians.
The network is believed to involve at least 51 people. Police said it included the abuse of infants and at least one case of a suspect acknowledging abusing his own children.
The inquiry has seen three convictions in western Norway, said deputy police chief Gunnar Floystad.
The 31 other suspects are from other regions in the country.
Mr Floystad said he could not reveal more details pending the conclusion of the investigation, known as Dark Room, which began in 2015.
Prosecutors said the perpetrators met in the dark web, using encryption and anonymity to hide their tracks.
