Two leaked tapes have emerged on the internet where Kiev-appointed governor allegedly threatens an ex-presidential candidate who called for a referendum. The official may also be behind the Odessa massacre and Mariupol shootings, the leak adds.

On the first tape, which appeared on May 14, an oligarch and governor of the city of Dnepropetrovsk in southeastern Ukraine, Igor Kolomoisky, allegedly called ex-presidential candidate Oleg Tsarev and started threatening him. He told Tsarev to leave Ukraine immediately, saying it was in connection with the killing of Bogdan Shlemkevich, a soldier from Ukraine’s National Guard on May 9 in Mariupol, southeastern Ukraine. He was shot in clashes between anti-government protesters and soldiers sent by Kiev in an ‘antiterrorist’ operation in eastern Ukraine.

Tsarev, a Dnepropetrovsk businessman and People's Deputy of Ukraine, submitted his candidacy as self-nominee for the presidential election scheduled for May 25. He is standing for federalization of the country as well as for referenda in all parts of Ukraine. He withdrew his presidential candidacy on 29 April in a protest against Kiev.

“We prayed for [Bogdan] Shlemkevich who was killed in Mariupol and they say that Tsarev is guilty,” Kolomoisky told the ex-candidate.

The Dnepropetrovsk governor says that now Tsarev and his family will be hunted down and killed.

“They put $1 million for your head, they will go after you everywhere,” Kolomoisky told him. “Tomorrow they will look for your people and relatives,” said the Ukrainian oligarch.

The second leaked conversation, which also emerged on May 14, was between Oleg Noginsky, the president of the Suppliers of Customs Union, an organization which aims at increasing the turnover between Ukraine and the Customs Union of Belarus, Kazakhstan, and Russia, and someone whom he called Yan Borisovich. Noginsky said that Kolomoisky’s actions are mad.

“Besides, it was he [Kolomoisky] who hired the guys in the Odessa [massacre]… the situation went out of control. Their task was to beat them [anti-government protesters] so they would be taken to hospital and to destroy the camp [on Kulikovo Pole Square] completely,” he said.

Kolomoisky is still in Odessa and the result of his actions is that 16 of those who survived the House of Trade Unions bloodshed in Odessa were killed during the next three days, the man who is believed to be Noginsky accuses the Dnepropetrovsk governor.

According to him, it’s not the first time the Dnepropetrovsk governor has threatened politicians. He also allegedly threatened Igor Markov, a deputy of the Ukrainian parliament.

RT could not confirm the veracity of the tapes, and Oleg Tsarev was not available for comment at the time of publication. However, he confirmed to the website of Russian TV show, ‘Man and Law’, that this conversation took place.

In Odessa violent clashes erupted on May 2 between anti-government protesters and radicals supporting the coup-imposed authorities in Kiev. The confrontation led to a tragedy that left 48 people dead and over 200 injured as nationalists burnt the protester camp and then set fire to the Trade Unions House with anti-Kiev activists trapped inside. According to witnesses, many of those who managed to escape the flames were then strangled or beaten with bats by radicals. Several victims reportedly died of gunshots, while others burnt alive or jumped out of windows in a desperate attempt to escape the deadly flames.

Although the unrest in southeastern Ukraine has already resulted in dozens of deaths, the coup-imposed authorities in Kiev are continuing their crackdown on anti-government activists following pro-autonomy referenda in Ukraine's Donetsk and Lugansk regions.
