The prosecutor’s office in Geneva has launched a money laundering investigation into ousted Ukrainian president Viktor Yanukovych and his son Aleksander.
Police searched the premises of a company owned by Aleksander Yanukovych and removed documents.
“This investigation allows us to examine how these firms which are directly or indirectly connected to Alexander Yanukovich make their money in Ukraine, Holland or Switzerland,” said Chief Prosecutor Yves Bertossa.
It comes as Switzerland, Austria and Liechtenstein have frozen bank accounts and assests belonging to the two Yanukovychs as well as more than a dozen other Ukrainians.
Viktor Yanukovych denies having any foreign bank accounts, saying talk about them is“empty chatter.”
Ukraine’s new government accuses him of stripping state coffers bare and says tens of billions of euros have disappeared into offshore accounts.
