Prosecutor General Hisham Barakat on Thursday issued a gag order for the murder case of Shaima al-Sabbagh in all broadcast, printed and electronic media until the end of the investigation.
Information about the case will only be issued by the office of the Prosecutor General.
In a statement on Thursday, Barakat condemned the media for reporting inaccurate information that adversely affect the investigation.
Sabbagh was killed holding roses in downtown Cairo during a peaceful symbolic march to Tahrir Square to commemorate the martyrs of the revolution.
Activists hold the police responsible for her death, while the Interior Ministry denied involvement or summoning any police officer for investigation into the case.
Interior Mohamed Ibrahim said in a news conference, however, that he would personally assure that Sabbagh's death would be thorough investigated.
