Indonesian Security Forces were hunting for more than 200 inmates still on the loose after a mass breakout from an overcrowded prison on Sumatra Island.

More than 440 inmates fled the jail in Pekanbaru City Friday after Prison Guards let them out of their cells to pray. Police initially said about 200 inmates were involved in the breakout but later revised up the figure.

Footage on Local TV Stations showed many men, some wearing sarongs, scurrying out of the jail, with no sign of officials in pursuit.

Local Police spokesman Guntur Aryo Tejo said, authorities launched a massive manhunt and about half had been recaptured by yesterday evening, but Security Forces were still hunting for the rest.
