Riots broke out on Tuesday in Roumieh prison, the largest in Lebanon and located close to Beirut, days after two videos were released showing prison guards torturing inmates.
Security forces were called to end the riots and were deployed around Block A, where meetings began with an Interior Ministry representative, official Lebanese ANN agency reported.
The controversial footage depicting physical abuse was filmed in April amidst riots involving Islamist prisoners being transferred from one building to another.
The Lebanese authorities have assured that those found guilty of torture will be punished in accordance with the law.
Five of the guards who appeared striking the prisoners were arrested and transferred to the military prosecutor for further investigation, according to ANN.
Roumieh prison, built in the 1960s, is no stranger to such riots due to overcrowding, underfunding and generally poor living conditions.
In April 2011, large riots broke out and, after four days, required the intervention of security forces to restore control in the prison.
