The Prosecutor General's Office of Ukraine (PGO) and the Security Service of Ukraine (SBU) are again conducting investigative actions at the office of PJSC Ukrgazvydobuvannia, the company's press service has reported.

"Stability is a sign of quality. The holidays are over, and representatives of the PGO and the SBU are again at our Ukrgazvydobuvannia office. We do not know yet exactly why they came, we expect information. It's no longer funny," the company's press secretary, Larysa Polischuk, wrote on her Facebook page.

As reported, the PGO and the SBU had already conducted searches at PJSC Ukrgazvydobuvannia last year.

Ukrgazvydobuvannia is wholly owned by NJSC Naftogaz Ukrainy. It is the largest gas producer in the country, accounting for about 75% of the nation's total gas production.
