A tight security plan was adopted to secure the trial of former president Hosni Mubarak, his two sons Alaa and Gamal, ex-interior minister Habib el-Adli and six of his top aides, which will take place on Saturday, at the premises of the Police Academy in the district of New Cairo. According to the Interior Minister\'s plan, more than 3000 policemen and 15 armored cars will be deployed near the Police Academy to reinforce security measures during the trail which will be aired on Saturday by Egyptian TV. Mubarak, his interior minister al-Adli and six security chiefs are to face court again over their complicity in the murder and attempted murder of hundreds of peaceful protesters on January 25-31 2011. Mubarak\'s sons Gamal and Alaa - once symbols of power and wealth - will be retried on corruption charges along with their father. Business tycoon Salem is being tried in absentia. The initial trial in August 2011 was a big moment for the country and the region because it was the first time an Arab leader deposed by his people appeared personally in court. But the drama of those first days, which saw an ailing Mubarak wheeled into court on a stretcher, has since fizzled. In January, Egypt\'s highest court, the Court of Cassation, ordered a retrial for Mubarak after accepting an appeal against his life sentence, citing procedural failings. Adli had also been sentenced to life over his involvement in the deaths of the protesters, but controversially his security chiefs had been acquitted, sparking widespread anger and protests after the verdict in June.
