On July 15, 1983, while serving as head of the Armenian Secret Army for the Liberation of Armenia's French branch, Garabedian planted a bomb inside a suitcase at the Turkish Airlines check-in desk in the south terminal of the Orly Airport in Paris.
[1] During the trial in Créteil, France, he was defended by Jacques Vergès while the victims of attack were represented by Gide Loyrette Nouel.
[7] Garabedian denied his earlier confession of having planted the bomb, but was found guilty (along with Nair Sonner and Ohannes Semerci) and sentenced to life imprisonment on March 3, 1985[8] for such "deeds that were aimed at Turkish targets".
[12] Many prominent Armenian intellectuals, including Zori Balayan, Silva Kaputikyan, Sos Sargsyan, Gevorg Emin, Perch Zeytuntsyan, Levon Ananyan and others expressed support of Garabedian.
[13] According to Armenian media, Garabedian was unofficially "supervising" the Yerevan-Dilijan transport line and with his guards was a part of a criminal incident in 2010.
