Islamist activist Ahmed El-Mogheer is to face trial for attacking protesters at the presidential palace in December 2012.

El-Mogheer appears in video footage holding a baton amid clashes between pro- and anti-Morsi protesters in the vicinity of Itihadiya Palace in Cairo.

The clashes, dubbed Bloody Wednesday, resulted in ten deaths, including journalist El-Husseiny Abou-Deif, and hundreds of injuries.

The opposition blames El-Mogheer for the death of Abou-Deif. They claim he acted as an informer, reporting on anti-Morsi activists during the clashes.

The date for the trial at Cairo Misdemeanor Court has not been set.

El-Mogheer was summoned earlier this month by Qasr El-Nil prosecution for questioning on other clashes.

Two weeks ago, El-Mogheer and other Brotherhood supporters reportedly attempted to forcibly break-up a sit-in of intellectuals calling for the dismissal of Morsi-appointed Minister of Culture Alaa Abdel-Aziz, who has attracted the ire of many members of Egypt’s arts and culture scene in recent weeks with his sackings of high profile officials.

El-Mogheer recently stated on his personal Facebook page that he "can't wait for 30 June" to give 'the remnants of the old regime the final blow." 

Mass anti-Morsi protests are being planned for 30 June. Islamist groups, including the Brotherhood, reject the protests as attacks on the president's legitimacy planned by a minority of representatives of the former Mubarak regime.
