Giza prosecution ordered on Monday the detention of a lower-ranking policeman for four days pending further investigations on charges of attempted murder and use of excessive force after he shot a microbus driver using his work weapon during a street brawl in 6 October city.
The policeman reportedly shot the man in the legs during the confrontation.
The driver told the prosecution the brawl started after he challenged the policeman for issuing him a ticket for a traffic violation that he did not commit.
In the past months, several police personnel, in particular lower-ranking policemen, have been involved in shooting of civilians during personal or work-relarted arguments.
Last week, a lower-ranking policeman was detained after shooting dead a microbus driver in Cairo's suburb of Maadi as he intervened to break up a fight between the victim and another driver.
In August parliament passed amendments to police laws to regulate the performance of all security services. These changes emphasise the need for policemen to respect human rights, the government said.
