The ruling which came yesterday found the defendants guilty of attacking the Kerdasa police station on August 14, 2013, the same day when Egyptian security forces dispersed two Brotherhood protest sit-in camps in Cairo and Giza, killing hundreds of people.
They were also found guilty of the attempted murder of 10 other police personnel, sabotaging the police station, torching a number of police vehicles and possessing heavy firearms.
Out of the 188, only 135 were present while the rest were tried in absentia.
Defence lawyer Bahaa Abdel-Rahman told Ahram Online that among the defendants were two persons who died during the trial, but who weren't dropped from the trial, along with a minor.
