MOSCOW, August 7 - RAPSI. The Tverskoy District Court has extended until October 7 businessman Viktor Baturin's arrest on attempted fraud charges, the court told the Russian Legal Information Agency (RAPSI/rapsinews.com) on Tuesday.

Thus, the court has satisfied the investigation's appeal.

Baturin is the elder brother of business woman Yelena Baturina, the wife of former Moscow Mayor Yuri Luzhkov and Russia's richest woman. Forbes ranked her as the world's third richest woman in 2010 with a $2.9 billion fortune. Viktor Baturin and Yelena Baturina are the co-founders of the Inteco investment and construction corporation.

Baturin has been charged with attempted fraud involving Inteco promissory notes. He was earlier charged with the attempted theft of 10.8 million rubles ($341,670).

Baturin's case carries other charges involving the attempted theft of over 5.6 billion rubles ($177.16 million).

Baturin was detained at Inteco's office on November 28 after arriving to cash a counterfeit 10.8 million ruble ($341,670) promissory note. Investigators charged Baturin with attempted fraud the next day and sent the case to court.

Baturin has not admitted to the crime.

He faces up to 10 years in prison.
