Two aides to Egypt's former president, Mohamed Morsy, were released two weeks after they were arrested and detained.
The presidential aides were reportedly confined along with Morsy at an undisclosed location after the former president was ousted in an army-led overthrow on 3 July.
Morsy's assistant for political affairs, Pakinam al-Sharqawy, is now at home, according to Muslim Brotherhood spokesperson Ahmed Aref.
The ex-president's social communication adviser, Emad Abdel Ghafour - also chairman of the Salafi Watan Party - was also released.
Following his release, Abdel Ghafour said he planned to devote his time to "worship," adding that the current climate was not an encouraging one for politics.
Aref stressed that other Brotherhood members, comprising staff of the Morsy administration and Ettehadiya Presidential Palace, were still in detention.
Aref told Al-Masry Al-Youm that "keeping Brotherhood members in detention will make the group more adamant on proceeding with its efforts to retrieve legitimacy and reinstate Morsy."
He urged the army to immediately disclose Morsy's whereabouts.
Earlier on Wednesday, army spokesperson Ahmed Mohamed Ali assured that Morsy and his crew had been well treated, adding that the former president has not been under detention, but was rather kept out of sight for his own safety.
