The 33-year old Damian Rubiales Carrasco told security officers that there was a bomb in his backpack, causing the evacuation of more than 200 people from the airport, Sputnik International reported.
According to the Estonian Postimees newspaper, Carrasco was sentenced by the Harju county court the same day, after five police patrols have not found anything suspicious at the scene.
The Spaniard, who was facing up to five years of imprisonment under Estonian legislation, stated in his defense that his threat was only a joke.
