"Acting on intelligence inputs that the Maoists were trying to set up their base along the Kalahandi-Phulba border, we launched an attack on them. About 30-40 Maoists led by central committee member Jampanna escaped on seeing the police team," said Jethwa adding that there was no casualty in the police team. Jampanna carries a reward of Rs. 25 lakh on his head. The combing operation has been intensified in the forest reserve. The police have recovered Maoist literature, kitbags, solar panels, radio sets, batteries and 18 rounds of ammunition after the operation, said Jethwa.
