The surrendered ultra, identified as Suka Majhi (20) of Mulunga village under Bijapur district of Chhattisgarh, had been inducted into the banned outfit six years ago by Maoists, Kalahandi SP Brijesh Rai and Deputy Commandant CRPF 64 Battalion Suryamani Behera told reporters.
Majhi, who was present at the press meet, said he had been imparted training by the red rebels in Chhattisgarh and later brought into Odisha to operate in Malkangiri, Koraput, Rayagada and Kalahandi districts.
Recently Majhi, who carried a reward of Rs one lakh on his head, was operating in Karlapat, Gundi and Kahandual mali Reserve Forest areas, the SP said.
Majhi alleged that he was subjected to harassment and on many occasions had faced assault by senior cadres.
Gradually, he got disillusioned with the organisation and was looking for an opportunity to quit.
Along with him, two other local militia members who were providing support to the Maoist cadre working in their area under duress, also gave themselves up, the senior official said adding their identity was not disclosed because of security reasons.
