Austria rejects U.S. request to extradite Ukrainian tycoon Firtash
One of Ukraine's most influential oligarchs, Firtash, 49, was arrested in Vienna a year ago at the request of U.S. authorities, which have been investigating him since 2006.
He was released from detention in March 2014 after posting bail of 125 million euros (91 million pounds).
