Abu Sawyer Misdemeanors Court in Ismailia governorate on Saturday sentenced 19 policemen in relation to the Al-Mostakbal Central Prison break that occured on October 21.
The defendants received punishments ranging from 1 to 2 years in prison, while 3 others have been acquitted.
Four police officers were sentenced to two years in prison, while 15 other defendants received one year each.
The defendants faced charges of gross negligence in permitting prisoners to escape from the facility.
One senior police officer and one civilian were shot dead and a low-ranking policeman was injured on October 21 when six prisoners escaped from the Al-Mostakbal prison.
According to security sources, three of the fleeing prisoners were affiliated with the terrorist group Ansar Beit al-Maqdis (also known as "Sinai Province"), and the other three had been convicted of various crimes.
Major Mohamed al-Hussainy, chief detective at Abu Sawyer police station, was killed while chasing the fugitives; and one civilian passerby, named Ahmed Rizk, was also killed during the chase.
The jail-break started with one prisoner claiming he was ill. When the jailer opened the door of the cell, the perpetrators snatched his pistol, shot him in the thighs and fled the scene.
Using pickup trucks, over 10 armed elements allegedly helped the fugitives in their getaway, showering the prison with bullets from automatic weapons.
The sentenced policemen hold various ranks, including colonel, major, and first lieutenant, while most are from the lower ranks.
