An Egyptian appeals court overturned on Monday the convictions of 77 supporters of ousted president Mohamed Morsi.
The court ordered a retrial for the 77 defendants who were originally sentenced to between five to ten years in prison.
The incident goes back to 26 July 2013, in the coastal city of Alexandria's Al-Qaed Ibrahim Square.
Pro-Morsi supporters protested in the square, denouncing the Islamist president's ouster on 3 July 2013.
Clashes broke out between Morsi supporters and opponents and later between Morsi supporters and the police from the other.
The defendants were charged on a number of counts, including thuggery, rioting, murder, attempted murder, demonstration of force, possession of weapons, blocking roads, sabotaging public and private properties, among others.
The events led to the death of 12 people and left 180 others injured.
Following Morsi's ouster, Egypt's judiciary declared his group, the Muslim Brotherhood, a terrorist organisation.
Police have launched a crackdown on his supporters, arresting thousands mainly on protest-law related charges.
Morsi is currently imprisoned in a number of cases including espionage with Hamas and Qatar. So far he has been sentence to both death and life in prison. His sentences are currently in appeal.
