Vice President Boris Levin and Andrei Yermilov have been charged with abduction and extortion, among other charges.
"The decision can be appealed in a higher court within three days," a Basmanny district court judge said.
Levin's defense attorney said the charges related to a certain "Vlaskin" in the provincial central Russian town of Tambov, and denied his client or any of his associates had "threatened Vlaskin."
According to media reports, investigators believe Levin and Yermilov abducted Euroset shipping agent Vlaskin in 2003. The Kommersant daily quoted a Euroset source as saying that Vlaskin had stolen large batches of mobile phones, which he then allegedly sold in an outlet he had opened for the purpose. The source said Vlaskin had bought several flats, cars and even a yacht with the money.
Vlaskin's alleged crimes were exposed as a result of internal investigation, reports say, following which the shipping agent fled. He was placed on the police wanted list, but the company's security service were the first to find him and "persuaded" him to repay the money they said he had stolen from Evroset, the source said.
Defense lawyers representing Levin and Yermilov said they would appeal the court's decision.
