SSP H N Singh told PTI today that following an FIR lodged by jailor of the prison, police have registered a case against unidentified miscreants and a search operation in this connection has been initiated.
As per preliminary investigations, police suspect an old enmity behind the crime as the chief warden had got threats from some miscreants after confrontation over meeting with undertrial prisoners, he added.
Chunnilal (50), was shot dead by unidentified miscreants when he was returning home from jail duty yesterday.
