Lithuania’s Financial Crime Investigation Service (FNTT) is searching the offices of Nemunas Dawn leader Remigijus Žemaitaitis, his colleague Daiva Petkevičienė and the party headquarters, prosecutors said on Thursday.
The investigation, which has been ongoing since March, focuses on potential fraud.
Authorities are examining whether a crime was committed when Žemaitaitis and Petkevičienė leased their personal vehicles to the party while continuing to use the cars themselves.
No formal charges have been filed at this stage.
Nemunas Dawn, a populist party, is part of the Social Democrat-led governing coalition.
