The inquiry was also directed at the charges of corruption during his tenure at the helm of Egyptian leadership.
There are conflicting reports about his condition as some reports indicate that he is fit enough to be questioned at the hospital in the Red Sea resort of Sharm el-Sheikh, while some others say that he was in Intensive Care Unit (ICU) after a "heart crisis" during interrogation.
Egypt's national television stated that Mubarak was in intensive care while Al Arabiya TV quoted a manager at the hospital saying that the former ruler is fit enough to be questioned.
Meanwhile, reformists in Egypt have taken to the streets once again alleging that Mubarak was was being protected from prosecution by Egypt's military rulers. Reuters reported that dozens of people gathered outside the hospital at the Sharm el-Sheikh resort and chanted, "We want our money. We want the thief to be tried."
Mubarak who ruled Egypt for 31 years on the trot before being oustered by the popular revolt in Feb 2011, has suffered from numerous health problems in the recent years. The octogenarian had been to Germany in Mar 2010 for a gall bladder surgery.
Prior to being forced to step down, Mubarak had vowed to die in Egypt.
