A senior aide to the prosecutor-general, Sumar Nasiza, told RFE/RL that Tanaev was facing charges of corruption and abuse of office.
"The Prosecutor-General's Office opened several criminal cases against Mr. Tanaev. It has been reported in all mass media that he was charged in absentia with abuse of office and illegal use of budget funds and it was decided, in his absence, that he was to be arrested as a preventive measure," Nasiza said.
Prosecutors later agreed not to detain him while they investigate in exchange for a written promise that he will not attempt to leave the country.
Tanaev's lawyer, Maxim Maximovich, said his client denied any wrongdoing.
Tanaev has returned to the country from voluntary exile in Russia, where he had fled following the protests in March that led to the ouster of President Askar Akaev.
The Prosecutor-General's Office has also charged two members of the former president's family with corruption -- his son, Aidar Akaev, and son-in-law, Adil Toigonbayev.
