Hosni Mubarak's two sons were charged Wednesday with insider trading and referred to trial before a criminal court.
A statement by the prosecutor-general's office carried on the state news agency official said the two, along with seven others, made illicit gains from the sale of a bank.
It gave no other details.
Mubarak and his two sons, one-time heir apparent Gamal and wealthy businessman Alaa, are already in prison and on trial on charges of corruption. A verdict is expected on June 2.
Mubarak himself faces additional charges of complicity in the death of some 900 protesters during the uprising last year that ousted him. But his sons do not face those charges. Mubarak could get the death penalty if convicted on the charges linked to killing protesters.
Mubarak stepped down in February last year and was arrested along with his two sons in April last year.
One of the seven men charged along with the Mubarak sons is the son of Mohammed Hassanein Heikal, Egypt's best known political writer and a longtime confidante of the late Egyptian leader Gamal Abdel-Nasser.
A date for the trial has yet to be announced and it was not immediately known whether any of the other seven people charged in the case are in custody.
