The arrest of Federation entity President Zivko Budimir was just the beginning of breaking up the widespread corruption network, Zubac said in Saturday's edition of Dnevni Avaz daily.
SIPA has filed a "huge number" of reports related to corruption "against state companies, responsible persons, against ministers, their deputies and assistants," he said.
Zubac would not name the persons and the institutions, saying the Federation was seeking 70 million convertible marks from the International Monetary Fund to cover the gaps in the budget and that there was "a person or a group that has defrauded the state of that amount."
"We did our job. The State Prosecutor's Office is doing its job together with us. If someone wasn't arrested today, it doesn't mean they will be free tomorrow. Justice is claiming its due," Zubac was quoted as saying.
He dismissed claims that Budimir's arrest was politically motivated, adding that those defending him in public "aren't defending Budimir but themselves."
Zubac also said that SIPA and the Intelligence and Security Agency had recently carried out three operations to prevent terrorist activities by members of the radical Islamic Wahhabi movement and that the cases had been referred to prosecutors.
