The South Cairo prosecution announced Thursday it would begin investigations into leading Muslim Brotherhood member Essam El-Erian on Saturday.
El-Erian, who was arrested Wednesday, faces multiple charges of inciting the murder of protesters on separate occasions: at the Presidential Palace in December 2012, at the Brotherhood headquarters on 30 June and in the Manial neighbourhood against members of a popular committee on the same day.
The leading Brotherhood member was referred to the criminal court for his charges in both the Brotherhood headquarters and the Presidential Palace clashes.
Other defendants on the trial related to the Presidential Palace clashes, scheduled for 4 November in Cairo, include ousted president Mohamed Morsi.
The ongoing trial in the Brotherhood headquarters case, however, was indefinitely adjourned following the decision by the panel of judges presiding over the proceedings to withdraw from the case for conflict of interests.
El-Erian is detained pending investigation on a number of other charges all related to incitement to violence.
