JAKARTA, Nov. 29 (Xinhua) -- Altogether 113 inmates broke out from a jail in Indonesia's westernmost province of Aceh after damaging barred windows in the wall amid heavy rains, a spokesperson of Indonesia's Legal and Human Rights Ministry said Thursday evening.
Trisno Riyanto, senior police officer overseeing security in Aceh capital of Banda Aceh, said so far police have arrested four of the escaped inmates.
The jailbreak in Aceh's Lambaro penitentiary occurred around 6:30 p.m. local time (1130 GMT), said Ade Kusmanto, spokesperson of Directorate General of Penitentiary of Legal and Human Rights Ministry.
The inmates broke the window bars with dumbbell and other heavy things to get out from jail, he said.
"Our focus now is to prevent other inmates trying to escape," Ade was quoted by local media as saying.
Measures to prevent riot inside the jail are underway, he added.
Aceh provincial police have also deployed personnel to assist in pursuing the escaped inmates, he said.
