An influential Ukrainian oligarch arrested in Vienna on an American warrant charging him with bribery and other offenses has been released on 125 million-euro ($172.5 million) bail by an Austrian court.

The Vienna state court said Friday that Dmytro Firtash promised not to leave Austria while extradition proceedings are underway and to be reachable to judicial authorities.

Firtash was arrested in Vienna on March 12. The U.S. attorney's office says he has been charged in an "international corruption conspiracy" in Illinois.

Firtash's company, Group DF, has said his arrest is not linked to current tensions in Ukraine, but to investigations connected to an investment project dating back to 2006.
