"The pre-trial investigation concerns possible influence peddling in the Labour Party's case heard by the Supreme Court," Martynas Jovaiša, chief prosecutor of the Organized Crime and Corruption Investigation Department at the Prosecutor General's Office, told reporters.
He said that suspicions of large-scale influence peddling would be brought against Aliukonienė later in the day.
The prosecutors would not disclose any more details, at least for now. However, Jovaiša said that "there may be more suspects".
According to information available to BNS, a Supreme Court judge was questioned on Thursday as part of the probe.
