Police have raided 58 locations and arrested 48 people believed to be part of a cyber crime syndicate in Italy, Spain and Poland this week, reports Reuters.
They are suspected of stealing millions from bank accounts in Europe.
The report quotes a statement from Europol, the Hague-based police agency that carried out the sting, saying:
The parallel investigations revealed international fraud totaling 6 million euro accumulated within a very short time.
Assistance was provided by Belgian and UK officials for the operation, which took place on Tuesday.
