A Cairo prosecution office ordered on Tuesday the detention of two aides of deposed president Mohamed Morsi for 15 days pending investigations into their involvement in violent clashes last December.
Misr El-Gedida prosecution office, headed by Ibrahim Saleh, detained Ahmed Abdel-Ati, Morsi's ex-presidential office manager, and Ayman Hodhod, Morsi's ex-advisor for safety and crises management.
The two are being investigated for their alleged involvement in violent clashes between opponents and supporters of Morsi that took place outside the Ittihadeya presidential palace in Cairo's Heliopolis district in December 2012.
Those clashes, which broke out following protests against a constitutional declaration Morsi had issued in November 2012, left at least five killed and hundreds injured.
The prosecution accused Abdel-Ati and Hodhod of holding citizens against their will, questioning them, torturing them and threatening to kill them.
Both denied all accusations against them.
Abdel-Ati and Hodhod have been held with Morsi and a number of his aides at an unknown location since 3 July when the army ousted the president Morsi amid mass nationwide protests against him.
On Sunday, Rifaa El-Tahtawi, Morsi's former chief-of-staff, and Asaad Sheikha, Morsi's former deputy chief-of-staff, were detained for 15 days pending investigations into the same clashes.
On 26 July, a top Egyptian court ordered the detention of Morsi himself for 15 days pending investigations into his suspected collaboration with Palestinian Islamist group Hamas.
