The wife of ousted Egyptian President Hosni Mubarak has been detained for 15 days pending further investigations into corruption allegations, the state news agency reports. Suzanne Mubarak will be held in a Cairo prison, Egypt's Mena news agency says. Mrs Mubarak, 70, and her husband have been questioned over allegations of "illegal acquisition of wealth". The former president, who held power for 30 years, stepped down in February after weeks of protests. He has since been detained by Egypt's Illicit Gains Authority, on charges he abused his position to illegally acquire wealth. He is also accused of involvement in the killings of anti-regime protesters.
