"We found a new grave at Parulbari village near Maheshpur today. The police and Central Reserve Police Force have cordoned off the area," Superintendent of Police, Midnapore (East) Satyeswar Panda said.
"This is a freshly dug grave. We cannot dig it unless we get court orders," Panda said.
On December 5, CRPF had found five graves from Bidyapith village in the Communist Party of India-Marxist stronghold of Khejuri from where charred human bones and skulls were dug out the next day.
