The Egyptian authorities have ordered the detention of Suzanne Mubarak, the wife of Hosni Mubarak, the country’s former leader deposed in February.
Mrs Mubarak was questioned by prosecutors over allegations she amassed wealth illegally while her husband was in office.
At the end of the questioning session, which lasted almost three hours, Mrs Mubarak fainted, said Dr Mohammed Fatahallah, director of the Sharm el-Sheikh hospital where she was interviewed.
She was ordered to be detained for 15 days pending further investigation, but security sources are quoted by the Associated Press as saying that there are no instructions to move her to prison.
The Egyptian state news agency said Mrs Mubarak was questioned about $3.3m held in an account in her name and a luxury home she owns in Cairo.
Mrs Mubarak is in the Red Sea resort of Sharm el-Sheikh where her husband is being detained in hospital pending probes over corruption accusations. Their sons, Alaa and Gamal, are in Torah prison in Cairo over similar allegations. All have denied any wrongdoing
Mrs Mubarak kept a low profile during her husband’s early years in office, but later assumed a prominent role in social and charitable activities. She is thought to have been behind plans for Gamal, her younger son, to succeed his father as president.
Mr Mubarak is also expected to be questioned over the shooting of demonstrators during the popular uprising which overthrew his regime. More than 800 people were killed, mainly by police.
The government is keeping Mr Mubarak in hospital in Sharm el-Sheikh, on the grounds of his poor health. An official medical team found facilities at Torah prison hospital were not adequate for his condition.
Several prominent officials who served under Mr Mubarak – some pillars of his regime – are being detained in Torah.
