Police in western Switzerland have broken an online paedophile network operating in nearly 80 different countries.
At least 32 people across Switzerland are also under investigation, according to the Vaud cantonal police.
Several suspects were reportedly arrested in the United States in connection with the case, while one person in Switzerland was ordered to pay a fine.
A police official said cybercrime experts in Lausanne were alerted by Interpol more than a year ago that pornographic details were hidden on a website for hip-hop music run by a webmaster in western Switzerland.
The owner of the site apparently knew nothing about the illegal activities.
The case is said to be unique because of the huge amount of pictures and links on the site.
Last September police in eastern Switzerland busted a child pornography website which operated at least in four countries.
