MOSCOW, November 1 (RAPSI) - Summa Group owner Ziyavudin Magomedov and his brother, the company’s co-owner Magomed Magomedov, who are charged with organizing a criminal gang and embezzlement, have been additionally accused by investigators of stealing 300 million rubles ($4.6 million), RAPSI reports Thursday from Moscow's Tverskoy District Court.

According to investigation, the funds were stolen during the construction of a highway in South Siberia in September 2014.

Ziyavudin Magomedov and Magomed Magomedov are involved in the organization of a gang, embezzlement of 2.5 billion rubles (about $38 million at the current exchange rate) from the state budget and withdrawal of some of these assets abroad, investigators claim. Magomed Magomedov is also charged with illegal weapon possession. They have been detained along with ex-CEO of Intex construction company Arthur Maksidov. 

The defendants have pleaded not guilty to the charges.

Two more defendants in the case, who allegedly fled to the United Arab Emirates, were arrested in absentia and put on the international wanted list.
