Beni Suef Criminal Court has acquitted the former local security chief and ten police officers of killing protesters during the January 25 Revolution.
Those cleared are amongst some 200 police officers and former regime officials who have been tried or are still facing charges related to the killing of protesters during the revolution.
On Sunday, Egypt's Court of Cassation ordered a retrial of ousted president Hosni Mubarak and former interior minister Habib El-Adly, who were convicted for failing to prevent the killing of protesters during the revolution.
The retrial was ordered after the appellate court accepted appeals lodged by the two former regime figures.
However, Mubarak will remain in jail on charges recently brought against him concerning millions of Egyptian pounds worth of gifts that he and others received from the country's biggest state-owned newspaper, Al-Ahram.
