Egyptian state prosecutors on Friday ordered 21 female supporters of ousted president Mohamed Morsi remanded in custody for 15 days pending investigation into charges that they had "incited violence," a judicial source said.

The women were arrested on Thursday for participating in an all-female demonstration in the coastal city of Alexandria to demand Morsi's reinstatement.

The source said that the women also face charges of "disturbing the peace," vandalism and affiliation with "an outlawed group."

Alexandria security officials said that security forces had dispersed a protest in the city's Stanley district after demonstrators had blocked roads for an hour on Thursday morning.

Morsi -- Egypt's first freely elected head of state -- was ousted by Egypt's powerful military establishment on July 3 following massive demonstrations against his presidency.

He is due to appear in court on Monday where he will face charges of inciting the murder of protesters outside the Ittihadiya presidential palace late last year.

Morsi's supporters insist that the charges against the ousted leader -- like those leveled against other Islamist figures -- are politically motivated.

If Morsi is brought to trial, it will be the first time for the ousted president to be seen in public since his removal.
