Egypt's General Prosecution has ordered the detention of Muslim Brotherhood Supreme Guide Mohamed Badie for 15 days, pending investigations into his role during clashes between supporters of ousted president Mohamed Morsi and the police last July.
The July Nasr City clashes occurred as pro-Morsi protesters attempted to extend a sit-in in the nearby Rabaa Al-Adawiya square to Cairo's main flyover 6 October Bridge. The violence left tens of protesters dead, according to the health ministry.
Badie, along with several other Muslim Brotherhood leaders including deputy Khairat El-Shater, is also on trial for inciting the killing of protesters in clashes at the group's Cairo headquarters.
The leaders face another charge of inciting violence in Giza's Al-Bahr Al-Azam on 15 July, when five were killed nearby Cairo University during fire-fights between pro-Morsi protesters and unknown assailants .
