In April 2011, Mubarak was arrested by Egyptian authorities pending investigations on a murder charge.
On 24 May 2011, Public Prosecution in Cairo formally indicted Mubarak, and other six high-ranking officials of Egypt Ministry of Interior and former Minister Habib al-Adly, with complicity in murder of 225 protestors and attempted murder of 1800 protesters in various Egyptian governorates between 25 January and 31 January 2011.
On 3 August 2011, Mubarak pleaded not guilty to all charges.
On 2 June 2012, Mubarak was convicted by the Cairo Criminal Court of being an accomplice in murder as he failed to take reasonable measures, in his capacity of President of Egypt, to prevent the killings of the Tahrir Square protesters. Mubarak was sentenced to life imprisonment.
On 13 January 2013, the Court of Cassation of Egypt granted Mubarak’s appeal, quashed the conviction and ordered a retrial. Specifically, the court of first instance was found to have erred in law by configuring criminal responsibility for murder by omission as the criminal responsibility could only have taken place through affirmative actions.
On 11 May 2013, the retrial before the Criminal Court of Cairo commenced.
On 22 August 2013, was transferred to a military hospital in Cairo for army personnel.
On 29 November 2014, the Cairo Criminal Court dismissed the murder charges against Mubarak as it found the Prosecution’s decision to include Mubarak in the original indictment as politically motivated.
On 4 June 2015, the Court of Cassation of Egypt granted the Prosecution’s appeal on errors of law against the Criminal Court’s dismissal and order a new retrial.
On November 2015, the retrial against Mubarak commenced before the Court of Cassation of Egypt.
On 2 March 2017, the Court of Cassation of Egypt acquitted Mubarak from all charges.
