Cairo. Egypt’s former president Hosni Mubarak was transferred back to prison from an army hospital, yesterday, after he appeared fitter at his aborted retrial on charges of complicity in the killing of protesters in the 2011 uprising that ousted him.Mubarak’s transfer from the hospital was delayed because hundreds of supporters had blocked the road in front of the hospital late on Wednesday in protest against Mubarak’s return to jail, the Mena state news agency said.The retrial of Mubarak will start again on May 11, a Cairo appeals court said on Wednesday. A first attempt to hold the retrial collapsed on Saturday when the presiding judge withdrew from the case and referred it to another court.Mustafa Hassan Abdullah had been widely criticised for acquitting security men accused of attacking protesters in an incident in which crowds were charged at by men riding camels.Many Egyptians were angered when the 84-year-old Mubarak, who had been seriously ill last year, appeared in good health, smiling and waving to the public in court on Saturday, prompting calls for him to be put back in jail.The prosecutor general’s office said it had decided Mubarak would be returned to Torah prison on the outskirts of Cairo. Mubarak was transferred by car from the Maadi Military Hospital to the prison in a heavily guarded police convoy yesterday.RetrialA first attempt to hold the retrial collapsed on Saturday when the presiding judge withdrew from the case and referred it to another court. Mustafa Hassan Abdullah had been widely criticised for acquitting security men accused of attacking protesters in an incident in which crowds were charged by men riding camels.Many Egyptians were angered when the 84-year-old Mubarak, who had been seriously ill last year, appeared in good health, smiling and waving to the public in court last weekend, prompting calls for him to be put back in jail.Mubarak, 84, who ruled Egypt for almost 30 years before being toppled by the 18-day popular uprising in 2011, was convicted last June along with former Interior Minister Habib el-Adli of failing to prevent the killings of more than 800 demonstrators, rather than actually ordering them.Mubarak and Adli were sentenced to life imprisonment but the country’s highest appeals court ordered a retrial in January after accepting appeals from both the defence and prosecution.This time, the presiding judge will be Mahmoud Kamel El-Rashidi, a low-profile jurist.The same court will retry Mubarak’s two sons, Alaa and Gamal on separate charges of financial corruption at the same time, state news agency MENA reported. Six other top Mubarak aides will also be retried with the former ruler, Mena said.On Monday, a judge ordered Mubarak’s release on bail on the charges of complicity in the killing of protesters but he has remained in custody in a military hospital on separate charges of alleged corruption.
