Greek police have launched a manhunt for two inmates who escaped from Greece’s largest prison at Korydallos, Athens on Tuesday night.
The prison supervisory authority is urgently investigating the escape of the two Albanian nationals who are brothers.
The two men were serving sentences for theft and robbery and are said to have escaped by cutting through the bars in their cell window, then scaled the prison wall using a hook and a makeshift rope.
Prison authorities discovered the prison break Wednesday morning during roll-call.
An investigator will look into the incident separately to determine whether there was a dereliction of duty by prison officials, the Justice Ministry said.
"The Ministry had issued explicit directions to prisons for the holiday season,” it said in a message, to "intensify security measures and avert any criminal activity."
