Head of Jail Division of North Sumatra`s office of the Ministry of Law and Human Rights Amran Silalahi said the prisoners escaped after scaling down the jail wall.
He said that the wall was about 2.80 meters high so that when the riot and fire took place, the inmates could easily flee the prison. "The causes of the riot and fire are still under investigation," he said.
The Labuhan Ruku prison only has a capacity of 250 inmates, but it accommodates some 874 prisoners.(*)
