Former Egyptian President Hosni Mubarak is widely expected to be a free man by the end of the day Wednesday.This is after the country's prosecution office ordered his release. Mubarak's lawyer says he expects the former leader to return to his former residence within the next few days. The prosecutor says he ordered Mubarak's release after he accepted a petition by the former presidents lawyer for his freedom on the basis of time already served.The decision to release Mubarak ends nearly six years of legal proceedings against him. On March 2, Mubarak was acquitted on charges of killing protesters during the 2011 unrest. Egypt's Court of Cassation upheld an earlier verdict, making the acquittal final. The Court of Cassation is the highest court for criminal litigation in Egypt.
