Salah El-Din Ibrahim, the conscript who fired at and killed a microbus driver on suspicion of him undertaking a terrorist act, was released Saturday.
Ibrahim shot the driver and injured a passenger near a security checkpoint in Giza's 6 October City on Friday.
The conscript told the prosecution that he had fired several warning shots but the driver refused to stop and instead stormed the metal barriers of the checkpoint.
He added that he shot at him after he suspected he might have explosives in the vehicle.
Al-Ahram Arabic news website reported Friday that the driver was driving in the wrong direction and approached the vicinity of the police station. However, he did not attempt to fire at the police checkpoint and police investigations found no explosives in the microbus.
Security forces, along with the army, have been a target of terrorist attacks since the ouster of Islamist president Mohamed Morsi on 3 July 2013, killing scores of police and military personnel.
At first, the attacks took place in the restive Sinai Peninsula. Recently, they have been taking place in several Nile governorates.
Last week, four explosions hit Greater Cairo leaving six dead and 80 injured.
