As reported by Censor.NET citing Ukrainski Novyny, this was announced by head of the criminal investigation department (CID) of the National Police Volodymyr Ostapenko.
He said that Dniprodzerzhynsk crime boss 'Netrik' had found people among his team to commit the crime against Tetiana Chornovol. In particular, he named Zinchenko, Zaliubovskyi, and Kornilov as participants.
All of them, except Zaluibovsky, have been put on the international wanted list.
"Zinchenko is in Russia. He has been detained, extradition materials sent, but Russia refused to extradite and he had been released. The rest of them are outside of Ukraine as well," Ostapenko said.
Two of the suspects, Kotenko and Zaluibovsky, have been sentenced by court, he added.
Ostapenko also informed that suspects of kidnapping Euromaidan activists Yurii Verbytskyi and Ihor Lutsenko were in annexed Crimea and Russia. The National Police believe they will be able to detain and sentence them.
As reported, Boryspil city court of the Kyiv region in April 2015 released Roman Zaluibovskyi and Serhii Kotenko, who are suspected of beating up MP Tetiana Chornovol in December 2013, as informed by People's Front party.
Ukrainian citizen Andrii Zinchenko, another suspect in the case, has been granted temporary political asylum by Russian migration service.
