Hundreds of police officers held the rally in front of the interior ministry in central Cairo on Tuesday, complaining about the injustice of the ousted government.
Mubarak's police force -- widely viewed as corrupt and brutal -- have called for their former boss to be publicly executed.
Earlier on Monday, policemen marched to the interior ministry to protest at the deaths of more than 300 people during demonstrations against Mubarak's regime.
Policemen carried banners and placards that read -- apology for our performance during those protests.
Meanwhile, thousands of Egyptian protesters including union workers are also staging strikes across the country over low pay and corruption.
Days after the country's popular revolution, Egyptians are now saying that they are capable of tackling their own problems and that the US or Israel's influence is not acceptable, a Press TV correspondent reported.
Thousands of protesters in Cairo have also demanded the new military rulers to hand over power to a civilian government as soon as possible, stressing that demonstrations will continue until the army accepts the reforms.
