The National Anti-Corruption Bureau of Ukraine (NABU) will tackle a case on unblocking accounts of former ecology and natural resources of Ukraine Mykola Zlochevsky, NABU Director Artem Sytnyk has said.

"The first question we received when we visited London – the funds of Zlochevsky. It was unpleasant to answer it, but as far as I know the criminal case on the fact of lifting the arrest of these funds … is being transferred to NABU, and I hope that we will quickly and effectively investigate it," Sytnyk said at a press conference in Kyiv last week.

As reported, on July 7, 2015, Interior Minister of Ukraine Arsen Avakov informed on the creation of the department for return of assets obtained through corruption in the Interior Ministry of Ukraine.

Among top-priority tasks was the case of Zlochevsky.

Zlochevsky was Ukraine's ecology minister from June 2010 until April 2012. He owns assets in the Ukrainian oil and gas industry.

In April 2014, the UK Serious Fraud Office (SFO) froze those accounts. However, in January 2015, the Central Criminal Court of England and Wales unblocked the accounts of Brociti Investments Ltd owned by former ecology minister of Ukraine Mykola Zlochevsky in the amount of $23 million on grounds of dismissal of all charges.
