As UNIAN reported earlier, on February 25, investigative journalists with the Nashi Hroshi with Denys Bihus project unveiled the first part of their probe claiming that the son of Oleh Hladkovsky, then-First Deputy Secretary of the NSDC, was allegedly involved in large-scale embezzlement scheme in defense industry.

The investigation alleged that Hladkovsky Jr. and his partners conspired with government officials to buy parts for military equipment and weapons from Russian smugglers, as well as from warehouses of the Ukrainian army. The prices of spare parts, which often failed to meet quality standards, were overestimated. In collusion with the management of Ukroboronprom, Ukraine's defense giant, products were sold to defense plants, the investigation said. Thus, the group allegedly received from Ukroboronprom at least UAH 250 million. Journalists said Hladkovsky was part of the then-president Petro Poroshenko's entourage.

On March 4, Poroshenko signed a decree dismissing Hladkovsky from the NSDC post.

The Special Anti-corruption Prosecutor's Office opened criminal proceedings to verify millions-worth dealings in the defense sector, revealed by journalists.

On March 11, journalists published another part of the probe, according to which NABU in December 2016 had considered the contracts of Optimumspetsdetal with the Kharkiv Armored Plant to be suspicious and included the company in the list of fictitious firms, but later reversed the move.
