CAIRO - Former Egyptian President Hosni Mubarak arrived in the Police Academy in Cairo's outskirts for his retrial Saturday morning, state TV reported.

His two sons, Alaa and Gamal, as well as ex-Interior Minister Habib al-Adly also appeared in the court, waiting for their retrial.

Mubarak is currently serving life imprisonment for involvement in the deaths of protesters in January 2011 upheaval and other charges including corruption and profiteering.

On Sunday, Prosecutor-General Talaat Ibrahim Abdullah ordered extension of Mubarak's detention as interrogations revealed that he kept the public funds allocated for maintenance and other works in the presidential palaces for himself, his wife Suzanne Thabet and his two sons.

On March 3, the Cairo Appeals Court set April 13 to retry Mubarak, his two sons, the interior minister and six other officials from the former regime.
