At least one police officer was injured on Sunday afternoon during a militant attack on a police club in the Sinai Peninsula's Al-Arish.
A security source told Al-Ahram's Arabic website that the attack was carried out by unknown assailants driving a car without license plates.
Thirty-five-year old Sobhy Bakry was transferred to Al-Arish military hospital after being shot in his right shoulder.
Al-Arish witnessed another attack earlier on Sunday, when an armed group fired at Police Station 2. No injuries were reported.
Since the popularly-backed army removal of former president Mohamed Morsi on 3 July, hardline Islamist militants in the deserted province have intensified attacks on security checkpoints, exploiting a security vacuum that dates back to the ouster of autocrat Hosni Mubarak in 2011.
Over 23 security personnel and 10 civilians have been killed in North Sinai's Al-Arish by suspected jihadist militants since Morsi's ouster.
The Sinai is largely inhabited by Egyptians Bedouins, who have often been at odds with the central government in Cairo over lack of social and political rights.
According to security sources, the army has killed tens of alleged jihadist fighters since launching its latest crackdown against militancy in the Sinai.
