Three members of the Muslim Brotherhood were arrested in Monufia Province, north of Cairo, over taking part in illegal protests.
Scores of the Muslim Brotherhood member demonstrated without taking a police permission, chanting anti-state slogans.
Police troops managed to disperse the illegal protest and arrested three of them.
In December, an Egyptian court ruled the Muslim Brotherhood a terrorist organization, blaming it for a string of attacks in the country and banning all its activities nationwide.
