Egypt's prosecution ordered on Thursday the release of Mohamed El-Qassas, a prominent activist and deputy head of the Strong Egypt opposition party pending investigation.
The prosecution is accusing El-Qassas of joining an illegal group that aims to obstruct the law and the constitution and preventing state institutions and public authorities from performing their duties.
El-Qassas was arrested in February 2018.
In January 2017, El-Qassas was placed by a court on Egypt's terrorist list, which has around 2,000 names including former president Mohamed Morsi; and the Brotherhood’s spiritual leader Mohamed Badie.
El-Qassas who announced his resignation from the Brotherhood during the 2011 revolution, has been a prominent activist and member of the political bureau of the Strong Egypt Party, which was founded in July 2012 by its current head and former presidential candidate Abdel-Moneim Abul-Fotouh.
In December 2013, the Egyptian government designated the Muslim Brotherhood a terrorist organisation.
