Shadi Ghazali Harb, one of the youth leaders of the 2011 revolution, faces charges of "spreading fake news and joining a terrorist entity because of his posts on Facebook and Twitter", Abdul Rahman Haridi, who attended the interrogation, told AFP yesterday.
He was also a leader of the Al-Dustur party, from which he resigned in 2013.
"The prosecution did not specify what terrorist entity it is referring to, but it mentioned a number of other activists... including Amal Fathi," who was arrested Friday after publishing a video on Facebook criticising Egyptian institutions and sexual harassment.
Harb's interrogation was set to continue on Wednesday (today), his lawyer said.
Human rights organisations have accused President Abdel Fattah al-Sisi, re-elected in March with over 97 per cent of the vote, of seeking to silence opponents.
