This was announced by deputy head of the National Police of Ukraine, head of Kyiv police Andrii Kryshchenko in an exclusive interview with Interfax-Ukraine, Censor.NET reports.
He also said the shooter told the investigation his own version of events.
"He speaks short and says he wanted to make a gift," Kryshchenko said.
He said that the investigation has enough evidence to prosecute the suspect, while his motives and the alleged Russian trace will be established further into investigation.
Kryshchenko said law enforcers are looking into how this person was legalized in Ukraine and got his passports.
He said the main motive behind the crime is considered to be patriotic activity of the ATO volunteers Okueva and Osmaev.
In the evening of June 1, an attempt was made on the lives of Chechen volunteer fighters of Ukrainian Kyiv-2 unit, Donbas war participants Adam Osmaev and Amina Okueva in Kyiv's Podil district. The attacker passed himself as a foreign journalist who allegedly wanted to interview them, got close to them, opened fire from a gun, and wounded Osmaev. His wife Okueva, to protect herself and repulse the attacker, opened fire and gravely wounded the killer. Both men have been taken to hospital with grave wounds. Osmaev is convicted by Russia of alleged attempt on President Putin.
