CAIRO - An Egyptian prosecutor will end the detention of former first lady Suzanne Mubarak once she pays bail and returns some assets to the state, a judicial source said on Tuesday. Mubarak, who denies charges that she abused her husband's influence for unlawful personal gain, was admitted to hospital on Friday after suffering symptoms of a heart attack. She has returned a Cairo villa and gave authorities the power of attorney to withdraw up to 20 million Egyptian pounds ($3.37 million), which authorities said she held, from two bank accounts, according to state media.
