"The police is facing new challenges everyday, both traditional and non-traditional. We have to train our force to meet these challenges and modernisation also has to be done," Purkayastha said after taking over as the state police chief.
He said the ability of the force has to be increased and there should be more capacity building of personnel.
"Our job is to serve all sections of society," he said.
G M P Reddy handed over the charge to Purkayastha at the state secretariat Nabanna earlier.
