The ultra, who surrendered before police yesterday was identified as Jambo Mandingi (25) alias Walsi of Rajengipadar village under Narayanpatna police station jurisdiction.
The woman told the police that she was inspired by the ideology of Maoists but got disillusioned after realising that they have digressed from it. They extort money from traders, contractors and kill innocent people on charges of being police informers, police said quoting her.
Therefore, Mandingi decided to give uparms and return to the mainstream, said a police officer.
"She was involved in various offensives and was moving with Maoist leader Aruna. Her case has been recommended for approval for rehabilitation under the state government's surrender policy for Maoists," he added.
At least 10 Maoists, including Madingi, have surrendered in Koraput in past two weeks, sources said.
