Angry Egyptians have blocked roads and surrounded the local security headquarters on Thursday night after a police officer killed a taxi driver.
Egypts Interior Ministry media office also released a statement, saying that the killing was caused by an argument about the fare for officers ride in Cairo's populous el Darb el Ahmar district.
Tearful residents saw videos shared by the el Masry el Youm news website, saying the officer had insulted the driver and shot him in his head.
Egypt's state news agency announced that the police officer has been arrested.
The incident has made clear the ongoing tension caused by the behaviour of security forces in Egypt. Last week, Egyptian doctors organised a large protest over police officers attacking two emergency room doctors in a Cairo hospital.
Human rights group say that extensive impunity among the security force has brought on police brutality. Trials are usually not effective and sentences against security forces are reduced.
2011 popular uprising is one of the main reasons that has led to police abuse and brutality in the country.
The incident occurred after the body of an Italian student was found dead on a roadside in Cairo this month with cigarette burns and signs of torture. Italy has urged ones responsible to stand trial in court but Egypt has rejected the idea that security forces could be involved.
