"We have opened a new police post at Kotmi in February and it has proved to be very effective," Gadchiroli Superintendent of Police Sandip Patil told PTI over phone.
"The surrender operations may gather momentum after first week of August, post 'Shaheed Week' observed from July 28 to August 3," the senior officer said.
During Patil's tenure as district police chief, 37 Naxals surrendered in 2014, and 24 have done so this year so far.
