Nearly a decade after pro-democracy protests first roiled Tahrir square, political activists in Egypt face a severe new threat to their freedom of speech: a new law governing the use of social media.

The country’s so-called “Facebook law” has already led to the arrest of Egyptian journalist Ahmed Gamal Ziada. Ziada was taken into custody on January 29 at Cairo Airport while returning from Tunisia to finish applying to join the for semi-governmental Journalist Syndicate, an organization which provides official accreditation and legal support to journalists.

Ziada was first arrested in 2013 and charged with spreading false news while filming police violence against protesters in Al-Azhar University in Cairo. He was accused of a number of crimes, including joining a banned group and “engaging in violent protests” while he was working as a photojournalist for the online news network Yaqeen. He was acquitted and released 16 months later after being subjected to physical violence and torture during his detention.

After being detained on January 29, Ziada was charged with “spreading false news via social media” and placed in pretrial detention at the Giza Central Prison, Last month, he was granted release on bail, pending further investigation.
