SARAJEVO, August 22 (RAPSI) - Russian billionaire Oleg Deripaska's En+ group denied on Thursday the media information that Dmitry Potrubach, the Russian financial director of the Balkan country's biggest enterprise, has left Montenegro, RIA Novosti reported.

Potrubach, 44, was arrested on July 10 while attempting to cross the border with Serbia.

Deripaska's En+ group holds a 29.3 percent stake in the plant, while the Montenegrin government holds another 29.3 percent. The plant, which produces 120,000 tons of aluminum a year and employs 1,200 people, is bankrupt according to local media.

En+ said earlier in a statement the company regarded Potrubach's detention as an attempt to put pressure on the plants legitimate shareholders and investors.

"En+ Group considers as inadmissible and unacceptable the practice of a criminal prosecution by the Montenegrin authorities of representatives of foreign investors on absurd accusations," the company said.

Potrubach is accused of stealing electricity from the European power system, a charge the company considers as absurd, En+ said. Local daily Pobjeda said the amount of electricity involved was worth 9.64 million euros.
