Authorities uncovered new details in a sophisticated electricity-theft scheme that allegedly manipulated digital meters and the central DEDDIE information system, altering consumption data.

Investigators from the Organized Crime Directorate found interference in 88 digital meters. The Australian-based manufacturer of the devices said it was “the most sophisticated incident that has emerged.” Authorities also identified a case involving photovoltaic installations, where software allegedly inflated reported energy production. Investigators said the network served 104 clients across 14 prefectures, offering subscription-style packages and remote-control capabilities.

Authorities estimate the operation began in 2017 and caused €9 million in losses. Police attribute leadership roles to three people and named the 104 users as defendants. Clients included households and businesses, among them restaurants, fuel stations and fast-food outlets. Raids Tuesday targeted Thessaloniki, where the alleged leaders lived. Evidence was seized, and suspects were taken to prosecutors for criminal charges Wednesday.
