Egypt's Rebel (Tamarod) movement has said a suspect arrested late Wednesday in the aftermath of a shooting incident in Giza's Mohandessin district is a member of the group.
A live-fire fight erupted in and around a major commercial building on Battal Ahmed Abdel-Aziz Street late Wednesday afternoon after unknown assailants opened fire from a rooftop on an army/security checkpoint in the area.
Security forces moved in shortly afterwards and rounded up at least three suspected assailants, state news agency MENA said, including an alleged Tamarod member, Mohamed Anwar Masaoud.
"Our friend Masaoud is not Muslim Brotherhood nor a terrorist ... he was present [there] by chance," the grassroots movement, which spearheaded the 30 June protests that toppled Islamist president Mohamed Morsi, said in a statement on its official Facebook page.
Egypt has been racked by festering unrest since the overthrow of Morsi 3 July and a mid-August crackdown on protest camps by his supporters. Around 1,000 people were killed in the raid and over days of deadly clashes between Morsi loyalists and security forces that followed.
