Six supporters of the Muslim Brotherhood group were arrested in Alexandria over instigating violence.
The suspects were arrested in a protest eastern the Mediterranean city, chanting anti-police and army slogans, blocking roads and disrupting transportation.
Leaflets, urging people for staging protests in the first anniversary of dispersing pro-deposed president Mohamed Morsi's sit-ins in the Rabaa al-Adaweya and Nahda squares, were seized in their possession.
In December, an Egyptian court ruled the Muslim Brotherhood was a terrorist organization, blaming it for a string of attacks in the country and banning all its activities nationwide.
