MOSCOW, June 26. /ITAR-TASS/. Russia's Investigative Committee has sent materials for arrest of Governor of central Ukraine’s Dnipropetrovsk Region Ihor Kolomoisky to court, spokesman of Russian Investigative Committee Vladimir Markin told ITAR-TASS on Thursday.

Kolomoisky was earlier named a defendant in masterminding several crimes, including murders, use of banned ways and instruments of war, obstruction to professional activity of journalists and abductions.

“As long as the court rules on a measure of restraint to Kolomoisky, the Investigative Committee will give necessary instructions to law enforcement agencies to immediately find the location of the defendant and place him under arrest,” Markin said.

In his words, the Investigative Committee will also send to court materials for arrest of Ukrainian parliament-appointed Interior Minister Arsen Avakov.

Investigation of the criminal case continues. Russian detectives are working with people who came from Ukraine to southern Russia’s Rostov-on-Don Region, Russian Republic of Crimea, Belgorod, Voronezh, Bryansk, Kursk and several other regions. “More than 3,500 people have been questioned as witnesses, 1,747 people have already been found as injured parties,” Markin said.
