At least 150 inmates of the JPN Central Jail in the district today went on a 48-hour hunger strike demanding release of those convicts who have served their term, a senior jail official said.
Their demands also included "better food and facilities".
The inmates vowed to intensify their stir if the demands were not met by May 6 in their communication to the jail authorities, the official said.
They also said the inmates will be shifted to Hazaribagh Open Jail if they intensify their stir.
