On Saturday, Mironov, 33, was detained in the Armenian capital, Yerevan. US authorities suspect Mironov of laundering $50,000 and of an illegal technology transfer.
"Mironov has a round-trip ticket. He has a return ticket for tomorrow, for August 31. If the prosecutor's office does not summon him, we will leave for Russia," Nersesyan told RIA Novosti, adding that no summons has been received so far.
On Monday, the court denied the request of the prosecutor's office for Mironov's provisional detention. The prosecutor's office may file an appeal against the court ruling within five days.
