Protesters and rights groups have most recently accused police of using excessive force this past week during a wave of mass demonstrations in cities around the country called by opposition politicians, trying to wrest concessions from Morsi.
But many protesters go further, saying Morsi must be removed from office, accusing his Muslim Brotherhood of monopolizing power and failing to deal with the country's mounting woes. Many have been further angered by Morsi's praise of the security forces after the high death toll.
The chaos prompted Morsi to order a limited curfew in three provinces and the deployment of the military to the streets.
The main opposition National Salvation Front said Saturday that the "gruesome images" of Saber's beating requires the dismissal of the newly-appointed interior minister. The statement said that Ibrahim was sworn-in in early January, police have been using "excessive force" more frequently against protesters.
In an attempt to heap more political pressure on Morsi, the opposition said the assault comes as little surprise since the president called on the police to deal firmly with protesters, among them rioters.
Prime Minister Hisham Kandil said he visited Cairo's Tahrir Square and the area of the presidential palace Saturday, which were largely quiet after Friday's protests. He said those who are camped out there are neither protesters nor revolutionaries.
"Protesters do not torch, attack hotels, rape women, steal shops, they do not burn the presidential palace. These are not revolutionaries," he said.
In an impassioned speech Saturday carried live on Egyptian state TV, Kandil said the street violence and political unrest that has engulfed the country for more than a week is threatening the nation's already ailing economy.
"The Egyptian economy is bleeding," he said. "It is holding itself, but if this situation persists it will be dangerous, extremely dangerous. No government can govern a nation with this chaotic situation."
Foreign currency earners such as tourism and foreign investment have dried up in the past two years of political unrest. Foreign reserves currently estimate at around $15 billion, less than half of where it stood before the 2011 uprising that ousted Mubarak. The Egyptian pound has also lost around four percent of its value due to the turmoil and planned austerity measures threaten to curb subsidies relied on by millions of poor Egyptians.
Kandil called on the opposition to back away from any more protests or marches.
"The world is watching to see how we will deal," he said. "It is upon all political parties to pull their peaceful protesters from the streets now."
Also Saturday, Mubarak's former interior minister, Habib al-Adly, was found guilty of abusing his position to force police conscripts to work on his mansion and land on the outskirts of Cairo. Both he and former riot police chief, Hassan Abdel-Hamid, were sentenced to three years in prison and fined around $340,000. The verdict can be appealed.
Al-Adly is already serving time for corruption and was sentenced to life in prison with Mubarak for failing to prevent the killing of nearly 900 protesters during the 2011 revolt that ousted the longtime leader. Both men appealed, and will be given a retrial.
