The investigation itself, however, will be continued in order to identify those who could have leaked the information, the Office told BNS on Wednesday.
The suspicions against Giržadas were brought almost a year ago, in the spring of 2012.
In November 2011, just before the Snoras nationalization, the Lietuvos Rytas daily, citing anonymous sources, reported that "the Prosecutor General's Office has already signed search warrant at one of the banks and homes of their executives." Several days later, Snoras was closed down.
The then FCIS head Vitalijus Gailius and Giržadas were later subjected to lie detector test over the leaking of information about planned official actions in the Snoras case. Giržadas failed the test. After Gailius refused to sack his deputy Giržadas, the then Minister of the Interior, Raimundas Palaitis, withdrew permits for both of them to access classified information and they were subsequently fired.
