Egyptian security forces arrested Thursday Taher Mokhtar, a member of the Freedoms Committee at the Doctors Syndicate and a long-time revolutionary socialist activist, according to ‘Freedom for the Brave,’ a grassroots campaign for the release of political prisoners in Egypt.

According to a statement released on the campaign’s official Facebook page, security forces stormed Taher’s apartment in downtown Cairo, arresting him and a friend and taking them to the Abdeen police station.

The charges against the 30-year-old Mokhtar are unclear. 

Also on Thursday, authorities detained political activist and poet Omar Hazek for two hours at Cairo International Airport before releasing him. 

Hazek, who was on his way to the Netherlands to receive an award for freedom of expression, was told by authorities that he was barred from travel over “security concerns.”  

Hazek was released from prison in September by a presidential pardon. He was serving a two-year sentence for illegal protesting.

Security forces also raided the Giza headquarters of Masr Al-Arabia news website, arresting its administrative manager Ahmed Abdel-Gawad, reported Al-Ahram Arabic website.

Abdel-Gawad is accused of “spreading false news” and “inciting violence against the state” on the upcoming anniversary of the 25 January revolution. Police also confiscated seven computers used by the website.
