Egypt's Prosecutor General Talaat Abdullah announced Sunday that deposed former president Hosni Mubarak will be detained for an additional 15 days pending investigations over new charges related to the illegal use of state funds.

Mubarak, former first lady Suzanne Mubarak, and their son Alaa Mubarak, are accused of seizing and facilitating the seizure of public funds, specifically funds allocated annually to be spent on presidential palaces.

Mubarak and his former interior minister, Habib El-Adly, are set to face a retrial 13 April after both were handed life sentences in June 2012 in connection to the killing of protesters during the January 25 Revolution.

A court accepted Mubarak's request for a retrial in January. El-Adly, and six of his aides who were acquitted in the initial trial, will also be retried.
