MOSCOW, April 6 (Reuters) - AIM-listed Russian oil producer Sibir Energy SBE.L said it is suing two ex-directors, including core shareholder Shalva Chigirinsky, in connection with unauthorised payments.

The claim currently stands at $328 million and is expected to rise to $400 million, the company said.

The company said it and two subsidiaries launched the claim in the Russian High Court in connection with alleged unauthorised payments Sibir had highlighted in February.

Sibir also said it believed its share price had been manipulated from Oct 16 to Oct 31. The shares are expected to remain suspended for the foreseeable future.

A Russian newspaper reported last month that oil and real estate tycoon Chigirinsky had given up his main Russian businesses and left the country for the United States. [ID:nLU201963]
