KIEV, December 6 - RAPSI. The Ukrainian Tax Service's investigators are nearing completion in the investigation of a criminal case against former Prime Minister Yulia Tymoshenko accused of failure to disclose over $165 million in foreign currency proceeds, the service reported on Monday.

Meanwhile Tymoshenko is reviewing expert examination reports.

A Kiev district court sentenced Tymoshenko on October 11 to seven years in prison for abuse of power in signing gas contracts between Ukraine's Naftogaz and Russia's Gazprom in 2009.

Soon after the sentence was declared it was reported that tax police had resumed four criminal cases opened against Tymoshenko over tax evasion in late 1990s when she headed the United Energy Systems of Ukraine.

Tymoshenko has been charged with organizing a non-disclosure of foreign currency proceeds amounting to more than $165 million, public funds embezzlement and tax evasion in the amount of over 47 million hryvnias ($5.8 million). These four cases have been consolidated into one.
