Police in Toronto say 341 people have been arrested and nearly 400 children rescued in a three-year investigation into a child pornography ring.
At the centre of the inquiry was a Toronto-based firm that allegedly sold DVDs and streamed videos of naked boys in Germany, Romania and Ukraine.
Azov Films marketed the footage as "naturist" and claimed they were legal in Canada and the US.
The films were distributed in 94 countries, police said.
Some 100 arrests were made in Canada and 240 in other countries, police said.
The head of the company, identified as Canadian Brian Way, 41, has been in custody since his arrest in May 2011, following an undercover operation, local media report. (BBC)
