Four were acquitted on Wednesday from charges of  illegal protesting against deposed Mubarak’s verdict last month.

On 29 November, Cairo Criminal Court acquitted Mubarak of corruption charges and dropped charges of aiding in the murder of protesters in the 2011 revolt that ended his 30-year rule.

Following the verdict, over 1000 went to Tahrir Square, the cradle of the Egyptian 2011 uprising, to protest. However, the Square was closed by security forces, so protesters took to the nearby Abdel-Moneim Riyad Square instead.

A controversial protest law, passed last year, mandates protesters notify authorities at least three days before protesting or else face heavy fines and prison terms.

The police violently dispersed the protest, two protesters died and nine were injured.

Around 85 were arrested during the dispersal. All protesters were released except for four who were referred to trial and acquitted on Wednesday.
