Prosecutor's spokesman Saparbek Nurpeisov said General Alnur Musaev is wanted in connection with the kidnapping and suspected murder of two officials from Almaty's private Nurbank. Musaev's whereabouts are unknown.
The case revolves around the abduction in January of former Nurbank officials Zholdas Timraliev and Abilmazhen Gilimov.
Timraliev's wife says her husband quit Nurbank in January after a disagreement with the man who had controlled the bank at that time, Rakhat Aliev. Timraliev and Gilimov have been missing since then. Authorities says they suspect Timraliev and Gilimov may have been murdered.
Musaev had been a close associate of Aliev, who also is the former son-in-law of President Nursultan Nazarbaev. Aliev has been charged by Kazakh authorities with kidnapping and assault in the case.
Aliev was arrested in Austria, where he had served as the ambassador from Kazakhstan. But Austrian police released Aliev after he posted bail of 1 million euros ($1.35 million).
Austria has refused Kazakhstan's requests to extradite Aliev, questioning whether Aliev would be able to get a fair trial in Kazakhstan.
