Former Mongolian President Nambar Enkhbayar was released on bail on May 14 after staging a hunger strike.
Enkhbayar, who was arrested on corruption charges on May 13, is now reported to be recovering in hospital from his week-long hunger strike.
Enkhbayar denies the corruption charges, which his supporters say are politically motivated. He had been planning to stand in Mongolia's June 2012 elections as the leader of a new political party.
His family released a statement on April 17 denying the corruption charges filed against Enkhbayar, and claiming that his civil rights had been abused by the Mongolian government.
Enkhbayar was president of Mongolia from 2005-2009 until he was narrowly defeated by current president Tsakhiagiin Elbegdorj in the 2009 elections. He previously served a prime minister between 2000 and 2004.
