Ousted Egyptian president, Mohamed Morsi, has been accused of complicity in the deaths and torture of demonstrators outside his presidential palace in 2012, judicial sources say.
On Monday, Egypts prosecution extended Morsis detention for another 15 days which starts from next week. He already stands accused of crimes related to his 2011 escape from jail.
In December, 2012, violent clashes erupted between Morsis supporters and opponents in the capital, Cairo, after he issued a controversial constitutional declaration in November of the same year to expand his powers.
On December 5, five people were killed in the clashes between backers and opponents of Morsi in the capital.
Earlier in July, a court in the Arab country ordered Morsi's detention over allegations of collaboration with Palestinian resistance movement, Hamas, to undertake aggressive acts in the country, as well as attacking police facilities, officers and soldiers.
On August 12, the Egyptian Judiciary extended the Morsis detention pending an inquiry into his alleged links with Hamas.
Morsi was due to be questioned on whether he collaborated with Hamas in attacks on police stations and prison breaks in early 2011, when he and some members of the Muslim Brotherhood escaped from jail during a revolution against the regime of former dictator, Hosni Mubarak.
Hamas reacted to the allegations on July 26 and condemned Morsis detention, saying it is based on the premise that the Hamas movement is hostile.
The movements spokesman, Sami Abu Zuhri, noted, This is a dangerous development, which confirms that the current powers in Egypt are giving up on national causes and even using these issues to deal with other parties -- first among them the Palestinian cause.
Egypt plunged into chaos after the head of the countrys armed forces, General Abdel Fattah al-Sisi, ousted Morsi on July 3, suspended the constitution and dissolved the parliament.
