KIEV, April 25 – Ukraine's Ihor Kolomoisky is among four prominent businessmen facing a $380 million worldwide freezing order that ties up property including his luxury French villa, months after he settled a multi-billion-pound claim in an unrelated case in British courts.

Ihor Kolomoisky and fellow billionaire Hennadiy Boholiubov are accused by Tatneft, a Russian oil company, of illegally seizing control of a refinery joint venture in Ukraine and siphoning hundreds of millions of dollars into their shell companies, according to documents filed at a London court. Two wealthy associates of the Ukrainians were named by state-controlled Tatneft in the suit that is seeking more than $334 million from the men.
