A police sergeant has been shot dead in Helwan on the outskirts of Cairo, Aswat Masriya reported.
A source from the interior ministry said unidentified suspects fired gun shots at the sergeant's private car on Thursday morning.
A passenger, the sergeant's sibling, was all injured by gun shot.
The suspects fled on foot.
The motive for the attack is unconfirmed.
Thursday marks the first anniversary of the violent dispersal protest camps by supporters of ousted Islamist president Mohamed Morsi, which caused over 600 deaths.
Egypt has witnessed a wave of militant attacks against police and army targets since the ouster of Morsi last July and the crackdown on his supporters. Over 500 security personnel have been reported killed since then.
