Public prosecutors ordered the release of Tahrir TV Channel anchor Dina Abdel Fattah on Sunday on a bail of EGP 5,000.
Abdel Fattah was being investigated along with the editor-in-chief of her programme Khairy Hussein for hosting members of the Black Bloc on her show The People Demand.
The report accused Abdel Fattah of promoting the “terrorist ideologies” of the Black Bloc, a group of masked vigilantes who have appeared among protesters in recent clashes with police.
Members of the Syndicate of Media Professionals protested against the bail, which Abdel Fattah refused to pay, but the prosecution said the bail had to be paid to release the defendants.
The syndicate eventually paid the EGP 10,000 bail for both Abdel Fattah and Hussein.
The Black Bloc had threatened on Saturday to break into the presidential palace on 11 February, the second anniversary of Mubarak’s removal.
They posted on their Facebook page: “To Morsi: Leave or Chaos.” They said they will storm the palace at 3.30pm.
The Black Bloc are calling on the people to participate in civil disobedience. The Black Bloc had closed down the Mogamma building in Tahrir Square for two hours on Saturday, and there are calls to close it down again on Monday.
