Cairo ( CNN ) -- Former Egyptian President Hosni Mubarak was admitted to a hospital Tuesday after complaining to his doctor that he felt unwell , according to a spokesman for the Egyptian military . A military source said Mubarak 's condition was stable , not critical , and that his wife and elder son were with him . Egyptian state television reported Mubarak suffered a heart attack during questioning over possible corruption charges . When contacted by CNN , however , the prosecutor 's office denied any reports Mubarak had been questioned by authorities Tuesday . Egypt 's health minister , Ashraf Hatem , later said that Mubarak 's condition was stable enough to allow prosecutors to resume questioning at the hospital , according to the state-owned Al Ahram newspaper . The military announced early Wednesday that `` questioning of former President Mohamed Hosni Mubarak and his family has started today . '' Mubarak proclaims his innocence . Mubarak was hospitalized at Sharm el-Sheikh International Hospital , state media reported . He and his family are believed to have been living on his estate in the Red Sea resort since February 11 , when he stepped down and handed power to the military . The hospitalization comes two days after Egypt 's chief prosecutor summoned Mubarak for questioning on corruption charges . Mubarak immediately decried the accusations , saying the probe is aimed at tarnishing his reputation and that of his family . In a brief audio message aired Sunday , Mubarak promised he and his family would account for everything they own . He said he agreed to allow the prosecutor to contact governments around the world to take `` proper legal steps '' to reveal whether he or his family own any property or real estate outside Egypt . Mubarak was brought to Cairo for questioning last month , and Egypt 's attorney general issued an order to freeze the assets of Mubarak and his family , and prohibited them from leaving the country . Egyptian blogger 's sentence is slammed . Mubarak had back surgery in Germany in 2004 , and returned there in 2010 to have his gall bladder removed . He had largely withdrawn from public view in recent years , until this year 's uprising prompted him to make televised speeches . Mubarak ruled Egypt for nearly three decades . His regime was toppled by a groundswell of popular protests that began January 25 . CNN 's Samson Desta , Caroline Faraj , Ivan Watson and journalist Mohamed Fadel Fahmy contributed to this report .
