A day after deposing the nation's first democratically elected president, Egypt's top prosecutor opened an investigation into claims that deposed President Mohamed Morsy and top leaders of the Muslim Brotherhood incited violence and the killing of protesters.

The prosecutor, Gen. Abdel Maquid Mahmoud, issued an order preventing Morsy and 35 others from leaving the country while they are under investigation, state-run Middle East News Agency and EgyNews reported Thursday, citing the prosecutor's office.

The news came as Egypt's security forces moved to arrest leaders of the Muslim Brotherhood who supported Morsy's rule and to silence their communications outlets.

Muslim Brotherhood spokesman Gehad El-Haddad told CNN that Morsy was initially under house arrest at the presidential Republican Guard headquarters in Cairo and later moved to the Ministry of Defense; the military has not commented on Morsy's whereabouts.
