More than 300 people have been arrested following the take-down of one of the world's "largest dark web child porn marketplaces.

BBC reports the site had more than 200,000 videos which had collectively been downloaded more than a million times.

It was shut down last year after a UK investigation into a child sex offender uncovered its existence.

But officials revealed that 337 suspected users had been arrested across 38 countries.
