In February 2011, ABC News reported that experts believed the personal wealth of Mubarak and his family was between US$40 billion and US$70 billion from military contracts made during his time as an air force officer. The Guardian reported that Mubarak and his family might be worth up to US$70 billion garnered from corruption, bribes and legitimate business activities. The money was said to be spread out in various bank accounts, including some in Switzerland and the UK, and invested in foreign property. The newspaper said some of the information about the family's wealth might be ten years old. According to Newsweek, these allegations are poorly substantiated and lack credibility.
On 12 February 2011, the government of Switzerland announced it was freezing the Swiss bank accounts of Mubarak and his family. On 20 February 2011, the Egyptian Prosecutor General ordered the freezing of Mubarak's assets and those of his wife Suzanne, his sons Alaa and Gamal Mubarak, and his daughters-in-law Heidi Rasekh and Khadiga Gamal. The Prosecutor General also ordered the Egyptian Foreign Minister to communicate this to other countries where Mubarak and his family could have assets. This order came two days after Egyptian newspapers reported that Mubarak filed his financial statement. Egyptian regulations mandate government officials submit a financial statement listing their assets and sources of income while performing government work. On 21 February 2011, the Egyptian Military Council, which was temporarily given the presidential authorities following 25 January 2011 Revolution, said it had no objection to a trial of Mubarak on charges of corruption.
On 23 February 2011, the Egyptian newspaper Eldostor reported that a "knowledgeable source" described the order of the Prosecutor General to freeze Mubarak's assets and the threats of a legal action as nothing but a signal for Mubarak to leave Egypt after a number of attempts were made to encourage him to leave willingly. In February 2011, Voice of America reported that Egypt's top prosecutor had ordered a travel ban and an asset freeze for Mubarak and his family as he considered further action. On 21 May 2014 a Cairo court convicted Mubarak and his sons of embezzling the equivalent of US$17.6 million of state funds which were allocated for renovation and maintenance of presidential palaces but were instead diverted to upgrade private family homes. The court ordered the repayment of US$17.6 million, fined the trio US$2.9 million, and sentenced Mubarak to three years in prison and each of his sons to four years.
The National Democratic Party of Egypt continued to state that Hosni Mubarak was to be the party's only candidate in the 2011 Presidential Election. Mubarak said on 1 February 2011 that he had no intention of standing in the 2011 presidential election. When this declaration failed to ease the protests, Mubarak's vice president stated that Gamal Mubarak would not run for president. With the escalation of the demonstration and the fall of Mubarak, Hamdy El-Sayed, a former influential figure in the National Democratic Party, said Gamal Mubarak intended to usurp the presidency, assisted by then Interior Minister, Habib El-Adly.
Protests against Mubarak and his regime erupted in Cairo and other Egyptian cities in January 2011. On 1 February, Mubarak announced he would not contest the presidential election due in September. He also promised constitutional reform. This did not satisfy most protesters, who expected Mubarak to depart immediately. The demonstrations continued and on 2 February, violent clashes occurred between pro-Mubarak and anti-Mubarak protesters.
On 25 January 2011, protests against Mubarak and his government erupted in Cairo and around Egypt calling for Mubarak's resignation. Mubarak stated in a speech that he would not leave, and would die on Egyptian soil. Opposition leader Mohamed ElBaradei paid no attention to Mubarak's remarks and labeled it as a trick designed to help Mubarak to stay in power. In a state televised broadcast on 1 February 2011, Mubarak announced that he would not seek re-election in September but would like to finish his current term and promised constitutional reform. This compromise was not acceptable for the protestors and violent demonstrations occurred in front of the Presidential Palace. On 11 February, then Vice President Omar Suleiman announced Mubarak had resigned and that power would be turned over to the Egyptian military.
On 28 February 2011, the General Prosecutor of Egypt issued an order prohibiting Mubarak and his family from leaving Egypt. It was reported that Mubarak was in contact with his lawyer in case of possible criminal charges against him. As a result, Mubarak and his family were placed under house arrest at a presidential palace in the Red Sea resort of Sharm el-Sheikh. On 13 April 2011, a prosecutor originally appointed by Mubarak ordered the former president and both his sons to be detained for 15 days of questioning about allegations of corruption and abuse of power amid growing suspicion that the Egyptian military was more aligned with the Mubaraks than with the revolution. Gamal and Alaa were jailed in Tora Prison; state television reported that Mubarak was in police custody in a hospital near his residence following a heart attack. Former Israeli Cabinet minister Benjamin Ben Eliezer told Israeli Radio that he had offered Mubarak refuge in the southern Israeli city of Eilat.
On 24 May 2011, Mubarak was ordered to stand trial on charges of premeditated murder of peaceful protesters during the revolution and, if convicted, could face the death penalty. The decision to try Mubarak was made days before a scheduled protest in Tahrir Square. The full list of charges released by the public prosecutor was "intentional murder, attempted killing of some demonstrators ... misuse of influence, deliberately wasting public funds and unlawfully making private financial gains and profits".
The trial of Hosni Mubarak, his sons Ala'a and Gamal, former interior minister Habib el-Adly and six former top police officials began on 3 August 2011 at a temporary criminal court at the Police Academy in north Cairo. They were charged with corruption and the premeditated killing of peaceful protesters during the mass movement to oust the Mubarak government, the latter of which carries the death penalty. The trial was broadcast on Egyptian television; Mubarak made an unexpected appearance—his first since his resignation. He was taken into the court on a hospital bed and held in a cage for the session. Upon hearing the charges against him, Mubarak pleaded not guilty. Judge Ahmed Refaat adjourned the court, ruling that Mubarak be transferred under continued arrest to the military hospital on the outskirts of Cairo. The second court session scheduled for 15 August. On 15 August, the resumed trial lasted three hours. At the end of the session, Rifaat announced that the third session would take place on 5 September and that the remainder of the proceedings would be off-limits to television cameras.
The trial resumed in December 2011 and lasted until January 2012. The defense strategy was that Mubarak never actually resigned, was still president, and thus had immunity. On 2 June 2012, Mubarak was found guilty of not halting the killing of protesters by the Egyptian security forces; he was sentenced to life imprisonment. The court found Mubarak not guilty of ordering the crackdown on Egyptian protesters. All other charges against Mubarak, including profiteering and economic fraud, were dismissed. Mubarak's sons, Habib el-Adly, and six senior police officials were all acquitted for their roles in the killing of demonstrators because of a lack of evidence. According to The Guardian, the relatives of those killed by Mubarak's forces were angered by the verdict. Thousands of demonstrators protested the verdict in Tahrir Square, Arbein Square and Al-Qaed Ibrahim Square.
In June 2011, Mubarak's lawyer Farid el-Deeb said his client "has stomach cancer, and the cancer is growing". Mubarak had undergone surgery for the condition in Germany in 2010 and also suffered from circulatory problems with an irregular heart beat. On 13 July 2011, unconfirmed reports stated that Mubarak had slipped into a coma at his residence after giving his final speech, and on 17 July, el-Deeb confirmed the reports. On 26 July 2011, Mubarak was reported to be depressed and refusing solid food while in hospital being treated for a heart condition and in custody awaiting trial.
