Online child sex probe leads to 337 arrests: UK

LONDON: UK and US authorities investigating a "dark web" child pornography site run from South Korea on Wednesday announced the arrest of 337 suspects in 38 countries.

Britain’s National Crime Agency (NCA) said the "Welcome to Video" site contained 250,000 videos that were downloaded a million times by users across the world. "The website monetised the sexual abuse of children and was one of the first to offer sickening videos for sale using the cryptocurrency bitcoin," the NCA said in a statement.

"The arrests were made in 38 countries including the UK, Ireland, America, South Korea, Germany, Spain, Saudi Arabia, the United Arab Emirates, the Czech Republic and Canada."

The investigations also involved South Korean National Police and Germany’s Federal Criminal Police. In Washington, the US Department of Justice said separately the site operated "the largest child sexual exploitation market by volume of content" when it was taken down.

"Welcome to Video" operated on the so-called "dark web", which can only be accessed by special software and is widely used to traffic various illegal content and products. The NCA said seven men have already been convicted in Britain since the first suspect was arrested in 2017.
