MOSCOW, September 2 (RAPSI) - Swiss authorities are going to file charges against four people with ties to Russian energy giant Gazprom who are suspected of bribery, money laundering and forgery, Tages-Anzeiger daily reported on Tuesday.

The names of the suspects have not been disclosed. One of them was reportedly a Gazprom’s manager from 1998 until 2008 while another one still holds a senior position in the company.

The charges may reportedly be brought against the suspects in the case by the end of the year.

The alleged bribes were paid between 2004 and 2006, and the money reportedly ended up in the bank accounts in Switzerland.

The scheme linked to the construction of the Yamal gas pipeline that connects Siberia to Germany allegedly involved ABB, Alstom and Siemens. Notably, kickbacks were allegedly paid to senior employees of Gazprom through Siemens Industrial Turbomachinery (SIT) company.
