Deposed Egyptian president Hosni Mubarak and his wife have been questioned over suspicions they illegally amassed vast wealth, government officials said.
Mr Mubarak has been questioned several times, but this was the first time his wife, Suzanne, faced interrogation.
A Justice Ministry statement said interrogators headed to the resort of Sharm el-Sheikh to quiz the couple about corruption and misuse of power.
A report by a financial oversight body said Mr Mubarak and his family had numerous bank accounts in foreign and local currencies, luxury apartments and palaces and valuable land holdings. Some estimate his fortune in the tens of billions of dollars.
Mr Mubarak denies the allegations.
He also faces charges over deaths of protesters during the popular uprising which toppled him on February 11.
