Former Minister of Culture Farouk Hosni was found innocent of illicit gain charges on Saturday by Giza's criminal court.
Hosni was accused of abusing his authorities to illegally collect a fortune from October 1987 to January 2011.
Last September, a Cairo administrative court had reversed a verdict freezing Hosni's LE9million ($1.5 million) worth of financial assets, with investigation by the Illicit Gains Authority failing to incriminate him.
Hosni, along with other former ministers, was placed under a travel ban following the January 25 Revolution, which ousted ex-president Hosni Mubarak in February 2011.
Recently, a number of former regime figures facing corruption charges were granted retrials, some of whom were also released on bail such as ex-secretary general of Mubarak's National Democratic Party, Safwat El-Sherif, and former minister of information, Anas El-Fiqqi.
Mubarak sons, Alaa and Gamal, were also acquitted of corruption accusations last year but they remain in custody facing other charges relating to alleged stock market manipulation.
