Polish security officials say a Russian citizen suspected of flying a drone over Polish government and president's buildings has been detained for questioning.

Warsaw police spokesman Mariusz Mrozek said Monday the man was detained on allegations he violated Poland's law that bans flying drones in cities without permission.

Natalia Markiewicz, spokeswoman for the Government Protection Office, said an officer spotted the drone flying in the guarded area around Prime Minister Beata Szydlo's office and of the nearby Belweder Palace, an office of President Andrzej Duda.

An Associated Press photographer saw a Porsche car with Moscow registration plates parked near Szydlo's office and then being driven away under police escort.

Warsaw's ties with Moscow are tense, especially over Russia's annexation of Crimea and support for separatists in Ukraine.
