The South Giza Prosecution has ordered the detention of Hazem Salah Abu Ismail, a hardline Islamist and former presidential candidate, for 15 days, pending an investigation into charges of inciting violence that led to the deaths of 21 people in clashes that erupted in Bein al-Sarayat, Giza.
Abu Ismail's interrogation at Tora prison lasted several hours.
Security forces arrested Abu Ismail at his home on Friday. Neither he nor his supporters resisted his arrest.
Abu Ismail was disqualified from the presidential race that brought ousted President Mohamed Morsy to power in June 2011 after reports that his late mother had held a US passport. According to Egyptian electoral law, a candidate's parents must both be Egyptian and not hold dual citizenship.
In April, he won a court case against the Interior Ministry after authorities failed to provide proof that his mother held dual citizenship.
