"And he received an answer when he was neutralized and apprehended. The National Police rapidly snapped into action. The investigation is now underway, the terrorist is being interrogated.
"The assailant, a resident of the Donetsk region, purposefully came from the occupied territory to attack the members of Turchynov's family.
"A set of bladed weapons was seized from the detained terrorist. He behaved arrogantly during the interrogation, issuing threats against Turchynov and state leadership, shouting that there are others who will finish what he has started."
