Huge raid to shut down 400-plus dark net sites
The BBC understands that the raid represented both a technological breakthrough - with police using new techniques to track down the physical location of dark net servers - as well as seeing an unprecedented level of international co-operation among law enforcement agencies.
Prof Alan Woodward a security consultant from the University of Surrey who also advises Europol, said that the shutdown represents a new era in the fight against cybercrime.
"Tor has long been considered beyond the reach of law enforcement. This action proves that it is neither invisible nor untouchable," he said.
