Anti-Muslim Brotherhood protestors gathered outside Cairo's main police headquarters after a suicide bomb ripped through the building earlier Friday, killing at least six people and wounding dozens.
The blast was one in a series of attacks on police in the Egyptian capital at a time of mounting confrontation between Islamists and the military-backed government.

"All the Egyptians are sad, sad because so far, unfortunately, the Muslim Brotherhood, and (former President Mohammed) Morsi and his accomplices are still sitting in prison and have not been executed," protestor Yasser Hassan said.
"Please have mercy on the Egyptian people," he pleaded. "These people have to be executed. The Muslim Brotherhood have to be executed."
The attacks only served to further heighten tensions one day ahead of the third anniversary of the 2011 uprising that toppled President Hosni Mubarak.
Rival rallies have been planned by both supporters of the government and their Muslim Brotherhood opponents.
"We are now going to secure Tahrir Square and all of Cairo's squares," Egyptian Interior Minister Mohammed Ibrahim said.
There was no immediate claim of responsibility for Friday's bombings, but the attacks reinforced the government's campaign to paint its top political opponent, the Muslim Brotherhood, as being behind a wave of terrorism that has escalated since Morsi's ouster last July.
Three years after the uprising in the name of democracy, Egypt remains locked in a fight between the new government and the Brotherhood.
In a statement, the Muslim Brotherhood condemned Friday's attacks and suggested the government did it as a pretext to crack down even harder on Brotherhood.
