He noted that a similar bomb was seized during the arrest of so-called 'Kharkiv guerrillas' who allegedly prepared the explosions the day before the parliamentary elections.
"We know for sure that it was plastic bomb of magnetic action, the same that we have previously seized, and exactly the same was brought into the bar," he said.
According to him, the investigation will be able to establish the performers and those who ordered the attack.
"We know the people who brought them and participated in previous terrorist acts. I firmly believe that we know who we're looking for, we know who delivered them, and who inspired these crimes," the SBU representative said.
