Egypt authorities accused of illegal random searches on phones
Activists say that police are randomly accosting pedestrians without a stated reason and searching the photos, videos and social media accounts on their phones.
One Egyptian activist wrote on Facebook that the heightened security presence in central Cairo meant that there are now police officers at every corner.
Unprecedented demonstrations calling for the ousting of Sisi erupted last week in Cairo, Suez and other Egyptian cities.
The protests were sparked by corruption allegations lodged against Sisi, his wife and the military by a former government contracter, now self-exiled in Spain.
Mohamed Ali has accused Sisi and his military of appropriating millions of dollars in public funds to build a colossal presidential palace and a number of luxurious villas.
At least 1,438 people have been detained since Friday in what has been dubbed the "Palacegate" revolution, according to the Egyptian Center for Economic and Social Rights.
Egypt's prosecution has so far sentenced more than 300 people to 15 days in prison over their participation in the protests.
