A Trinamool Congress-backed body opposing the acquisition of land claimed on Sunday to have found the charred body of a child at Bhangabera in Nandigram, scene of police firing on March 14.
The Bhumi Uchhed Pratirodh Committee's core committee member Sabuj Pradhan told reporters the body was found while the group's members were digging up land under Bhangabera bridge in the hope of finding bodies of those killed in the police firing.
He said the body would be handed over to police.
East Midnapur's Superintendent of Police G Srinivas said police had received reports that a body had been found in Bhangabera but were yet to get possession of it.
Earlier, the BUPC, comprising members of the Trinamool Congress, SUCI, Jamiat Ulema-e-Hind, Congress and BJP organised a large procession to demand 'punishment' for Chief Minister Buddhadev Bhattacharjee for the police firing on March 14.
Fourteen people, including women and children, were killed in police firing as farmers protesting against the setting up of a chemical hub Indonesia's Salim Group tried to prevent policemen from entering Nandigram.
The state government later said the project would not be set up in the area.
The protestors displayed banners that said - 'We do not want sympathy, we want punishment by hanging'.
They demanded that the CPI-M MP from Tamluk, Laxman Seth, should also be punished punished as he played an 'instrumental' role in the flare-up in Nandigram.
The procession, including a large number of women and children, covered a 10-km route from Garchakraberia to Bhangabera where the protestors dispersed after seeing a large posse of policemen.
Later, the protestors began digging up a large area under Bhangabera bridge while a huge police contingent monitored the situation.
Police said they were keeping a close watch on the situation in Nandigram.
A police contingent has been posted on Bhangabera bridge to monitor the situation, Srinivas said.
Trinamool Congress MLA Subhendu Adhikary told reporters that though Nandigram was limping back to normalcy, the situation at Khejuri continued to be volatile. He alleged that a strong contingent of CPI-M supporters had congregated at Khejuri.
