TV host Reem Maged was released from custody on LE500 bail on Monday.
Maged is accused of defaming the judiciary in her talk shows, particularly the criminal court that acquitted the six aides of former Interior Minister Habib al-Adly of killing protesters during the revolution.
There are currently 1,164 charges in the courts against journalists and state TV hosts that have been filed by judges accusing them of consistently defaming the judiciary.
Several media figures have been investigated in these cases, including TV host Hala Sarhan, according to the daily Al-Wafd newspaper published by the Wafd Party.
State-owned MENA news agency said that also on Monday, the investigating judge heard the testimonies of Shereif Amer and Lubna Asaly, both TV hosts at the privately-owned Al-Hayat satellite channel, as part of investigations into defamation charges.
