"Incidents of vote buying during the Seimas elections can have serious negative consequences," the committee said.
"Having taken this into account, the committee unanimously agreed to draw the Parliamentary Speaker's attention that such incidents might pose threats to national security, therefore, it is worth discussing the issue at the State Defense Council with the participation of representatives from competent state institutions," the committee said in a statement.
"As the Seimas run-offs are approaching, it is necessary to make immediate decisions on the issue," Arvydas Anušauskas, chairman of the committee, was quoted as saying in the statement.
The Lithuanian police have launched over a dozen of pre-trial investigations into alleged vote buying incidents during the first round of voting in the Seimas elections.
Zenonas Vaigauskas, chairman of the Central Electoral Commission, has acknowledged that the majority of the cases involve candidates of the Labour Party. He also said at a press conference on Monday that it was too early to say whether the violations could change the election results before the investigations were finished.
