Groisman knew from the SBU that his translator worked for the special services of the Russian Federation a few months before his arrest. This "Ukrainian Truth" became known from its own sources. SBU for several months "led" an employee of the Cabinet Stanislav Yezhov with the consent of Prime Minister Vladimir Groisman to document his contacts with Russian special services.

According to some reports, Groisman was even allowed to listen to conversations of an interpreter with a curator from the Russian Federation. He was detained after the SBU had information that he could hide. According to Yezhov's declaration, his wife Yulia Miroshnikova is a Russian citizen. As reported, the Security Service officers exposed the official of the secretariat of the Cabinet of Ministers in cooperation with the special services of Russia. The moment of his detention near the building of the Cabinet was shown by the television channel "Direct", a film crew who allegedly happened to be near.
