Yevhen Korniychuk, former deputy chairman of the Naftogaz Ukrainy board, has been notified of suspicion and put on the wanted list as part of the investigation into the case of the so-called 'Boiko's oil rigs'," Ukrainian Prosecutor General Yuriy Lutsenko has said.

"Today, deputy head of the Naftogaz Ukrainy board Korniychuk has been notified of suspicion and put on the wanted list," Lutsenko told a briefing in Kyiv on Friday.

The Prosecutor General added that Korniychuk is on the territory of Ukraine, but is fleeing from the investigation.

"We invite him to voluntarily come to the General Prosecutor's Office of Ukraine, which will obviously affect the qualification of his actions," added Lutsenko.

Korniychuk held the post of Deputy Chairman of the NJSC Naftogaz Ukrainy board from March 2010 and was dismissed from this post on June 26, 2013 at his own request. Prior to that, in 2004-2005, she held the post of Deputy General Director for Finance at Ukrgazvydobuvannia.

The case of 'Boiko's oil rigs' is a matter of buying overpriced rigs for oil and gas extraction on the Black Sea shelf, in which Yuriy Boiko, co-chairman of the Opposition Bloc faction, is allegedly involved.
