Three unknown attackers riding in a 4x4 vehicle yesterday opened fire on a policeman, killing him with four bullets. A civilian was also killed in the attack that left two other civilians injured, they said.
One of the attackers was arrested while the search is on to nab the other two, the sources added.
The forces also seized the vehicle of the attackers carrying a number of weapons, ammunition and a hand bomb in it.
The attacks, mainly targeting police and military, increased after the ouster of Islamist ex-president Mohamed Morsi in 2013 by military following massive protests against his rule.
Hundreds of police and Army personnel have been killed since then.
