i've heard the fight back against milton is under way. it's an unlikely hub for the high tech fight against the scammers. the cyber crime unit here, in contrast to the uk, is making arrests across europe and beyond. nice to meet you. welcome. using digital techniques, the team can follow the crime through the dark portals of the deepest parts of the internet and chase down those perpetrating it. it's directed by public prosecutors, methodically gathering evidence and forensically tracing the huge sums of money it generates. they are operating like professional legal companies. and that's what we say, this is organised crime. and how much money are some of these larger organised crime groups bringing in? probably hundreds of millions per year.
