ODESSA, May 14. /ITAR-TASS/. Unidentified persons have attacked an Odessa office of PrivatBank that belongs to pro-Kiev business tycoon Igor Kolomoisky.

The malefactors detonated a piece of a pipe filled with explosives and bolts in front of the bank’s office in Odessa, southern Ukraine, on Wednesday, May 14. The bank has announced a bounty of 50,000 hryvnias (about $4,000) for the attackers.

This is the third attack on PrivatBank offices in the Odessa region over the past 24 hours. Previously one office was set on fire and the bank’s ATM in a village was destroyed.

Kolomoisky had supported the Kiev authorities and then was appointed the governor of the Dnepropetrovsk region. He is also known for having offered a reward of 10,000 U.S. dollars for capturing supporters of federalization in the East of Ukraine.
