As reported by Censor.NET citing Ukrainski Novyny, this was said by NABU Director Artem Sytnyk.
"The search operations in Ukrnafta offices were indeed carried out today," he said.
According to him, the searches were conducted under criminal proceedings initiated into the company's activities.
However, a spokesperson for Ukrnafta said that no searches had been carried out in the company's main or regional offices.
The press service also said that the court ruling sanctioned searches in other companies.
As reported, in September 2016, NABU launched investigation into a doubtful accounts receivable in the amount of 7.745 billion hryvnia (about $280 million) generated by Ukraine's largest oil company Ukrnafta under crude oil sales contracts concluded at the auctions during March and October 2015.
