Plenković made the statement after a meeting of representatives of the parliamentary majority.
Five suspects, including an INA executive, were arrested last Saturday on suspicion of defrauding INA of more than one billion kuna by buying natural gas supplies from the company at below market prices and selling those supplies at market prices, thus making an illegal gain of at least HRK 848 million (approx. €113 million).
INA is jointly owned by the Hungarian energy group MOL and the Croatian state, with MOL being the biggest individual stakeholder.
