Egypt's interior ministry said on Saturday it has arrested three people who are running 23 Facebook pages, accusing them of using the website to incite against state institutions.
The ministry accused two men, both aged 27, and a 25-year-old women of being members of the Muslim Brotherhood.
Egypt outlawed the Brotherhood in 2013 after the ouster of Islamist President Mohamed Morsi.
Authorities have shown public concern over calls on social media to organise protests on 25 January to mark the fifth anniversary of the 2011 uprising that removed longtime autocrat Hosni Mubarak.
Social media, particularly Facebook and Twitter, played a large part in organising the 25 January uprising, as well as other protests since then.
Last week, President Abdel-Fattah El-Sisi warned against "any such protests," saying they could result in chaos.
A number of political activists have been arrested in the past few days in what is believed to be pre-emptive measures against "rumoured" protests ahead of the fifth anniversary of the 25 January Revolution.
