Alexandria Criminal Court postponed Saturday the retrial of Khaled Said's alleged killers to 31 August, when it will question two witnesses in the case.
The retrial, which began 1 June, comes after the two defendants, Mahmoud Salah Mahmoud and Awad Ismail Soliman, filed an appeal in December arguing that particular witnesses were "dealt with lightly."
On 1 June, the court ordered the release of the defendants after being detained for 35 months, exceeding the detention cap of 18 months.
Last October, the policemen were slammed with a seven-year jail sentence after being found guilty of illegal imprisonment and torture.
The family and supporters of the late 28-year-old Said were shocked at what they considered a light sentence.
The brutal murder of Khaled Said in summer 2010 in Alexandria is considered one of the sparks of the January 25 Revolution in Egypt.
