The deputy head of the pro-Morsy Wasat Party, Essam Sultan, was released pending the charges of inciting torture during the pro-Morsy Rabaa al-Adaweya sit-in.
Sultan faces charges of inciting the killing of three citizens in addition to inciting violence, torture and setting fire to a government-owned company building.
The defense asked that the defendant be released based on lack of evidence for his remanding and argued that the charges against Sultan are baseless.
