The killing of Ahmed Zaki in the capital's western suburb of October 6 was the latest in a spate of attacks by militants targeting the security forces since the ouster of Islamist president Mohamed Morsi last July.
Zaki, killed in the fifth such attack targeting police in Cairo within a week, was a commander in Egypt's central security forces, who have been at the forefront of a wide-ranging crackdown on Morsi supporters.
He was the third police general to be killed in attacks since the start of the year.
But the deadliest attacks in Cairo and other parts of the country, including the restive Sinai Peninsula, have been claimed by Ansar Beit al-Maqdis, a jihadist group inspired by Al-Qaeda.
