Egyptian-American journalist Mona Eltahawy posted to her Twitter feed around 11am ET: "Confirmed that Jihane Noujaim is free. Relieved!"
According to reports on Twitter, Noujaim and other protesters were charged with congregation and destruction of public property.
Noujaim is best known for her 2004 documentary "Control Room," which profiled pan-Arab news outlet Al-Jazeera.
Eltahawy was also arrested during the protests and suffered a physical and sexual assault that left her with two broken arms.
Protests continue today in Cairo's Tahrir Square, which they call "Last-Chance Friday." According to UPI, "Thousands joined demonstrations Friday in Cairo, the largest one demanding a civilian government in Egypt while a counter-protest supported the military."
