The United Kingdom's National Crime Agency has said that several online drug markets located on the dark web have taken down fentanyl product listings given the danger it poses to human life.
AlphaBay, a Dark Web marketplace for illegal goods, was shut down by authorities working across three countries. One of the site's main operators was arrested and later found hanged in his cell.
AlphaBay Market has been down since Tuesday and while site maintenance is not uncommon, silence from its admins and a sizeable $3.8 million withdrawal from the site's accounts have drawn suspicion.
Research, conducted at the University of Portsmouth, reveals that more than 80% of "dark net" internet traffic is generated by visits to websites offering child-abuse material.
