The Chhattisgarh State Congress has demanded the removal of nodal officer, Mukesh Gupta, of the investigating agency probing the May 25 ambush at Darbha area of south Chhattisgarh.

Mr. Gupta, an Additional Director General (ADG) rank officer, works in close liasonwith the NIA on behalf of the State.

According to police sources, Mr. Gupta, who heads the state intelligence, has only been providing “necessary backroom support” to the NIA and “not intervening in the investigation.”

The Congress however has been routinely challenging Mr. Gupta’s appointment alleging that he may “obstruct investigation.”
