GNR police have seized more than two tonnes of stolen copper and aluminium cable from regional scrap yards.
According to the police, 2,360 kilos of copper cable belonged to the communication company Portugal Telecom (PT), while 360 kilos of copper cable and 208 kilos of aluminium cable belonged to electricity company EDP.
The metal was found on April 12 in eight yards in Faro, Olhão and S. Brás de Alportel during an operation codenamed High Voltage.
During the raids, the border and immigration control authority (SEF) identified five Brazilian men who were in the country illegally and who they suspect were involved in the robberies.
Two were ordered to leave immediately while the others will be presented in court.
SEF also fined the scrap yard owners for hiring illegal workers.
