Executives at Latvian bank Norvik have claimed the nation’s central bank chief sought to extort money from their firm for years.

Central bank chief Ilmars Rimsevics faces a criminal investigation for bribery, but has not been charged so far.

Norvik filed an international complaint against Latvia in which it claims a “senior Latvian official” sought bribes from the bank and abused his power.

Norvik’s CEO, Oliver Bramwell, told The Associated Press: “The high-level official mentioned in our request for arbitration is Rimsevics.”

Company chairman, Grigory Guselnikov, also told the AP how individuals connected to Rimsevics had asked his bank to launder money from Russia.

Rimsevics is also on the highest policy-making council of the European Central Bank, which sets monetary policy for the 19 euro countries.
