As reported by Censor.NET, National Anti-Corruption Bureau Director Artem Sytnyk said in an interview with Pravovyi Tyzhden newspaper and Tsentr Novyn news agency.
"On the evening of May 27, the NABU received the report [of ex-Deputy Head of Ukraine's Security Service Viktor Trepak - ed.]. On May 30, we instituted criminal proceedings on the basis of these materials which are represented in the form of accounting information with a specified amount and the signature of a person put upon its receipt," he said.
"I did not quite understand why Trepak, an SBU officer, acted in that way... Instead of providing the information to the NABU and facilitating the investigation, he goes public, gives interviews, talks about some of the names, and then goes to the NABU. Some names have already been voiced in the statements of people's deputies. The suspects have been warned: they know about criminal proceedings opened against them," Sytnyk added.
"The investigation has been launched, we will collect evidence. However, we lost certain operational opportunities over publicity when names appeared in the mass media," the official stressed.
"We will not mention specific names, but a preliminary examination of these materials makes us believe some of the cases will be tried," Sytnyk noted.
Earlier, Petro Poroshenko Bloc (PPB) MP Serhii Leshchenko and journalists Anton Marchuk and Sevhil Musaieva-Borovyk published some of the documents proving the existence of Party of Regions' slush funds. According to the materials, the Party of Regions spent $66 million on political corruption over the second half of 2012.
Even earlier, ex-Deputy Head of the Security Service of Ukraine Viktor Trepak said he had given the information about Party of Regions' slush funds to the NABU.
