Community policing activities are being prioritised to involve the simple village folk.
Hemant Soren, Chief Minister of Jharkhand, has claimed, in September 2021, that as a result of the effective action against left wing extremism, the “presence of hardcore Maoists has been limited to mainly four regions, namely Parasnath Pahar, Budha Pahar, Tri-junction of Seraikela-Khunti-Chaibasa district in Kolhan division and some of the areas along the Bihar border”.
