More than 300 suspected pedophiles fell worldwide after an investigation into the dark web that trafficked tens of millions of child abuse videos.

The international police operation began with the arrest and conviction of 29-year-old Briton Matthew Falder—who obtained a master’s degree and a doctorate from the University of Cambridge—who tricked children into sending him naked photos, the Telegraph reported.

He then blackmailed them with publishing the images if they refused to carry out humiliating and degrading acts.

Once he bent his victims, he would record videos of the abuses and post them on a ‘Welcome To Video’ website for depraved people, managed from South Korea.

In this way, he contacted more than 300 potential victims, however due to his virtual mode of operation, he managed to evade capture for eight years.

An international working group began investigating the dark web platform used by Falder after he confessed his actions and was sentenced to 32 years in prison in February.

Welcome To Video site administrator Jong Woo Son Jr., 23, after being charged with nine counts in the United States all connected to the website, has been convicted and imprisoned in South Korea.

“They’re not as cloaked as they think they are, they’re not as safe as they think they are,” Nikki Holland, director of investigations at the National Crime Agency (NCA), told the Daily Mail.

“Dark web child sex offenders, some of whom are the very worst offenders, cannot hide from the police,” she concluded.
