As reported by Censor.NET citing Interfax-Ukraine, it was stated by NABU Director Artem Sytnyk at a news conference in Kyiv on Wednesday.
"The questioning of the plaintiff is almost over. After that, we'll start to identify these persons. In other words, our main task is to retrieve the handwriting samples in order to carry out expert studies," he said.
According to Sytnyk, Trepak passed almost 850 pages of materials to NABU detectives.
"In total, 841 pages have been provided, covering the period from 2008 to 2012," Sytnyk said and added that the Bureau will first of all deal with the largest amounts, gradually passing to smaller ones.
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 passed information about Party of Regions' slush funds to the NABU.
