MOSCOW, February 5 - RAPSI. The former management of the Moscow Metro will be investigated for fraud, the Interior Ministry's Moscow Department said on Tuesday.

The management is suspected of paying 800 billion rubles more than necessary for cleaning services.

"The head of the Moscow Metro reported that several companies contracted to clean stations from 2007 to 2010 overstated their expenses," the department said. "The fraud has resulted in over 800 million rubles in damages for the metro." The Moscow Metro management reported its findings on Monday.

Former Moscow Metro head Dmitry Gayev, who was earlier charged with abuse of office and is suspected of illegally receiving over 100 million rubles for a metro ticket system patent, died in late 2012. He was replaced by Ivan Besedin.
