Central Reserve Police Force (CRPF) soldiers had gunned down two Naxal commanders in retaliatory action during the April 24 attack Chhattisgarh's Sukma district when 25 jawans were killed in an ambush.
The revelation comes from 11 suspects who have been caught by the police for questioning in the last week's attack.
Some of the suspects broke out during interrogation and disclosed that the two dreaded naxal commanders were killed in the incident.
"During interrogation, some suspects revealed that two naxal commanders were killed in the Burkapal incident," Sukma Superintendent of Police Abhishek Meena told PTI.
He further claimed that those killed were identified as Anil, a commander of military platoon 24 of Maoists and divisional committee rank member, and Ravi, Cherla LOS (local organisation squad) commander.
While Anil was a native of Usoor area of the Bijapur district, Ravi was from Bhadrari district of neighbouring Telangana, the SP said.
CRPF and police officials had claimed earlier that several naxals were also killed in the Burkapal incident but their colleagues managed to drag their bodies inside the forests after the attack.
Preliminary interrogation has "established" that some of these suspects were allegedly involved in the Burkapal attack but once the interrogation process is completed, they will be arrested and produced before the court.
Their interrogation may reveal crucial details about the incident, he added.
