Four prison staffs of the Puzhal Central jail were hit with iron rods, plates and broken furniture for allegedly being not allowed to access mobile phones in the prison. Two prison staffers were also held captive for five hours and released after negotiations with the senior officials.   

Media reports suggest that remand prisoners in the high security wing were behind the attacks on staffers. Around 5:15pm on Friday, after prison officers took the prisoners back to their cells, jailor IIavarasam, assistant jailor Kumar, wardens Muthumani, Ravi Mohan and Selvin Devadass and electrician Maiyappan went into one of the cells to check if the inmates have cell phones with them.
