Two other suspects are an employee of the said Department and a representative of the Defense Ministry's Internal Audit Department.
Commenting on the detention of his deputy, Poltorak said his subordinate has nowhere to flee because Russia has opened three criminal cases against him for his participation in the Anti-Terrorist Operation in Donbas.
