Egypt's ex-president Hosni Mubarak has been placed in detention for 15 days, prosecutors say.
The statement from the prosecutor-general's office came after state media reported his two sons had also been detained as part of an inquiry into accusations of corruption and abuse of authority.
The information was posted on Facebook early Wednesday.
It said the ongoing investigation was into allegations of corruption, the wasting of public money, and the abuse of position for personal gain.
"The prosecutor general orders the detention of former President Hosni Mubarak and his sons Gamal and Alaa for 15 days pending investigation after the prosecutor general presented them with the current state of its ongoing investigations," it read.
