The defendants included three of the highest-ranking security officers in Alexandria, Ahram Online reported. They are Mohamed Ibrahim, who headed the security directorate in Egypt's second-largest metropolitan area; Adel El-Lakany, who headed the central security forces; and Wael El-Komy, the chief of investigations in the Raml district.
The court found all defendants not guilty on all counts. Prosecutors said the defendants encouraged police to use live ammunition, leading to the deaths of 83 people and wounding of at least 300 more.
The trial was moved out of the city after angry crowds set the Alexandria City Court on fire. It was held in the police academy in Cairo.
