The ministry said the light plane, which was piloted by a Lithuanian citizen and carrying a 22-23-year-old Lithuanian woman, belonged to a club in Kaunas, Lithuania's second largest city about 100 km (62 miles) west of the capital Vilnius.
"The plane that Belarusian air force detained carries the badge of the Kaunas air club and Lithuanian symbols," the ministry press service said.
The source also said that before detaining the plane, Belarusian air defense forces had sent emergency radio signals to the pilot but he failed to respond. Officers then asked Lithuanian air traffic controllers whether the plane had applied for an air route.
"The Lithuanian side said it had no idea about the plane," the press service said.
The low-flying intruder was registered at about 7 p.m. local time (4 p.m. GMT) Tuesday crossing Belarusian air space. A Su-25 Frogfoot interceptor scrambled and forced the airplane to land at a military air field in Lida in western Belarus near the Lithuanian border.
