A great scandal was caused by the forced suicide of Colonel Redl in 1913, when it was revealed that he was a Russian spy.

Colonel Redl was head of the counterintelligence of the Austro-Hungarian Empire until his suicide in 1913, which he committed himself on the orders of his own men. The news caused a great scandal, when it was revealed that he himself had been a Russian spy for the last ten years, since he had been blackmailed by the Russian Military Attaché into exposing his homosexuality.—mrtanaka
