Ousted president Hosni Mubarak, his sons, and former interior minister Habib El-Adly alongside six of his top aides have arrived at the Police Academy for their retrial session, MENA reported. Mubarak, who received a life sentence in June 2012 for failing to protect peaceful protesters during Egypt's revolution, was granted a retrial in January due to procedural irregularities in the initial trial. According to MENA, the number of people outside the academy is lower than in previous trial sessions. Security forces have separated the former president's supporters from the families of the martyrs of the 25 January 2011 revolution. In April, Judge Mustafa Hassan Abdullah, who was presiding over the retrial, recused himself from the case and referred it to the Cairo Appeal Court. Judge Mahmoud Kamel El-Rashidi was chosen to preside over the trial instead. A court ordered Mubarak's release pending the retrial, where he is accused together with former interior minister Habib El-Adly and six security aides of killing protesters during the revolution, but he is still in detention pending trial in two separate corruption cases. A Cairo court on Sunday upheld a 15-day detention order against Mubarak, which he had appealed, in relation to a corruption case brought by the Illicit Gains Authority. Both his sons Alaa and Gamal are on trial with him in this case. The 84-year-old is also being detained in another corruption case where he is accused of making private use of state funds allocated for renovating presidential palaces. Mubarak is currently in Tora Prison Hospital after Prosecutor-General Talaat Abdullah ordered his return there from Maadi Military Hospital.
