Lithuanian Prime Minister Gediminas Kirkilas said on Tuesday that his country had no spies in Russia, according to reports from Vilnius.
According to Russian media, Russia's Federal Security Service (FSB) on Tuesday detained an official in the Kaliningrad region accused of spying for Lithuania.
"We do not spy there," said Kirkilas. He added that Lithuania had been trying to keep good relations with its neighbors, including Russia.
Lithuanian Foreign Minister Petras Vaitiekunas also said that Lithuania would never act against its laws and related international law.
Earlier this month, Lithuania expelled the first secretary of the Russian Embassy in Vilnius, accusing him of involvement in "illegal intelligence activities."
In 2004, Lithuania ordered out the Russian military attache and two other diplomats for alleged intelligence activities. Moscow retaliated by expelling the Lithuanian military attache.
