According to the Ministry of Defense, the Russian government plane is suspected of violating Finnish airspace on Wednesday morning.
According to the ministry, the suspected airspace violation of the Mi-17 helicopter took place on the eastern border of Finland between Kesรคlahti and Parikkala on Wednesday morning at about 10.40.
The Mi-17 is a Russian-designed Russian helicopter.
The plane flew 4-4.5 kilometers into Finnish territory, the ministry added.
The Border Guard has started a preliminary investigation into the case.
"This is the second airspace violation committed by a Russian plane this year," Head of Communications at the Ministry, Kristian Vakkurisaid.
The previous airspace violation occurred on April 8 and involved a Russian state-owned passenger plane.
The Department of Defense only publicly reports violations of state, not civil, airspace.
The cities of Kesรคlahti and Parikkala are located about 20 kilometers apart, about 10 kilometers west of the Finnish-Russian border.
