Ousted Egyptian president Hosni Mubarak arrived in a helicopter early Saturday to New Cairo's Police Academy ahead of an expected verdict on charges of complicity in the killing of January 25 Revolution protesters.

Tens of Mubarak supporters and opponents gathered outside the Police Academy, where Cairo's Criminal Court is expected to issue its verdict in Mubarak's retrial.

Families of 2011 martyrs held pictures of relatives they lost while Mubarak supporters chanted slogans questioning if Egypt really became better following Mubarak's ouster.   

Mubarak, 86, is being retried on charges of complicity in the killing of around 850 unarmed protesters during the 2011 uprising that ended his 30-year rule. His sons Gamal and Alaa, Mubarak-era interior minister Habib El-Adly, and six of El-Adly’s aides are also charged in the same case.

The former autocrat was sentenced to 25 years in jail in 2012 for complicity in protesters’ deaths, but the verdict was successfully appealed in January 2013 as the presiding judge said there was not enough evidence presented by the prosecution.

Mubarak's retrial began in April 2013.
