Ziad Allouki, a former militia commander in the Tripoli neighborhood of Bab al-Tabbaneh, was released Friday from the Roumieh Prison after serving his sentence.
Allouki, who was the so-called leader of the Souq al-Qameh fighting frontier in Bab al-Tabbaneh neighborhood of the northern city of Tripoli, handed himself over to the army intelligence in May 2014.
He was charged with belonging to an armed group aimed at carrying out terrorist acts as well as killing and attempting to murder Lebanese soldiers.
In April 2014, the Lebanese army started implementing a security plan in Lebanon's northern city.
This comes after the Cabinet tasked the army and security forces with controlling the security situation in Tripoli and the eastern Bekaa Valley in areas bordering Syria.
Disputes from neighboring Syria's civil war inflamed back then sectarian grievances in Tripoli.
The clashes, which left scores of people dead, pit gunmen from both the mostly Sunni Bab al-Tabbaneh district that supports the uprising in Syria, and the Jabal Mohsen district which mostly comprises residents of Syrian President Bashar al-Assad's Alawite sect, a Shiite Islam offshoot.
