The Cairo Court of Appeal ordered Mubarak’s release after the expiry of the maximum temporary detention of two years, the reports said. He had been granted a retrial in the murder case, appealing against a life sentence.
Mubarak, who ruled Egypt for three decades, was ousted in a popular uprising in 2011.
He has been under arrest since April 2011 charged with complicity in the murder and attempted murder of hundreds of peaceful protesters on January 25-31, 2011. He is also facing several charges of corruption.
Defence lawyer Farid al-Dib made the case for his release on the grounds that Mubarak has spent two years in custody.
