Chhattisgarh DGP Viswa Ranjan in a news agency report said that the Maoists fired four rounds at the CRPF camp in Palampalli village, which was immediately retaliated by the security personnel.
Following the retaliatory fire, the rebels fled from the place. No casualty has been reported.
"This is nothing abnormal. This is a routine activity the Naxals indulge in," he said.
