Alexandria Criminal Court postponed the trial against police officials charged with murdering January 25 Revolution protesters in Egypt's second largest city till Sunday.

The prosecution presented 21 more suspects in the case and requested new hearings.

The trial is the last remaining on protesters killed in the 2011 uprising. The majority of verdicts in similar cases acquitted the accused.

Defendants face charges of killing 83 protesters and injuring hundreds during the January 25 Revolution.

The initial six suspects in the case included Alexandria's former head of the security directorate, Mohamed Ibrahim, former head of Alexandria's Central Security Forces, Adel El-Lakany, and former chief of investigations in Alexandria's Raml district, Wael El-Komy.

The prosecution accused Ibrahim and El-Lakany of inciting police and security personnel to shoot peaceful protesters using live ammunition and birdshot, to terrify and disperse other protesters.

The defence argued that the evidence provided by the prosecution is circumstantial.

The trial moved to Cairo after repeated clashes between the police and the families of those killed, which led to the torching of the Alexandria court and the recusal of the first panel of judges.
