If you know Alaa's case, you can skip this recap and jump to the horizontal line below. If you watched the interview with Yousri Fouda on OnTv, you can skip this post entirely.
Alaa was released on remand on Sunday 25th of December after spending 56 days in custody. Along with 27 other suspects who were accused of attacking the Maspero building and army forces protecting it. Read the full list of accusations here.
What happened on the 9th of October was that the Army attacked a peaceful march with extreme force, opening live fire on men, women and children and used at least 2 APCs to run over protesters. Around 27 protesters died and 1 soldier was killed with a bullet. After the deadly attack the protesters managed to burn an APC and clashes took place for few hours following the deadly episode.
You can read a first hand account of what happened here.
You can also watch this video by Mosireen about the events.
Alaa heard of the events over twitter and went to Abdelmoneim Reyad square, near Maspero, where he joined, well after the deadly events took place, the crowds chanting against SCAF. In one video he was filmed throwing a stone into blackness. Presumably at the police. He later went to the morgue of the Coptic hospital, where he instantly became useful. He spent the night their with the families of the deceased and helped them take the decision to allow for forensic autopsy and delay prayer and burial.
