The three witnesses who will testify in the trial are Security Forces Sheriff Mohamed Abdel-Hakim, Security Forces Sheriff Sergeant Abdel-Hameed Abou Yazeed, and former police officer Tarek Abdel-Menem who took part in the demonstrations and injured by bullets in his legs.

The trial started at 10:30 am (0830 GMT) amid disorder in the court, which led some civil plaintiffs leaving the trial. Clashes erupted outside the court among families of the killed in the Jan. 25 protest and policemen.
