In an accompanying press statement issued on Tuesday, the Austrian Ministry of the Interior said that Zaytsev had facilitated the “betrayal of state secrets” and that his actions had been “to the detriment of the Republic of Austria”. The arrest warrant accuses Zaytsev of having participated in the “intentional disclosure of a military secret”, but does not provide details. However, in a subsequent statement, Austrian police directly linked the search for Zaytsev with an espionage case that was reported in the Austrian media last year. The statement said that Zaytsev is believed to have recruited a man known as “Martin M.” to spy on Austria. This appears to refer to the arrest last November of a 70-year-old colonel in the Austrian Army, who was stationed in Salzburg. He is believed to have spied for Russia from at least 1992 until his arrest. Austrian media reported that the accused spy was believed to have given Russia information on a range of weapons systems used by the Austrian Army and Air Force, as well as the personal details of high-ranking officers in the Austrian Armed Forces.

Soon after the arrest of “Martin M.”, Austrian authorities arrested a second man, identified only as “O.”, who is also suspected on having spied for Russia. According to the Vienna Public Prosecutor’s Office, “O.” was an employee of the Austrian Office for Protection of the Constitution and Counterterrorism, known as BVT. He had been investigated on suspicion of espionage for more than a year prior to his arrest. The man’s arrest took place alongside simultaneous raids at two residential addresses associated with him, according to reports. No further details have been made available since the arrest. It is not known whether Zaytsev’s is also connected with the case of “O.”.
