The BJP's general secretary Kailash Vijayvargiya, who is the party's state in-charge, alleged that TMC workers supported by local police have been threatening its elected members with dire consequences if they do not either join their party or resign.
Deaths of over a dozen people in political violence had marred the panchayat polls on Monday even as the polling was held for 66 per cent of the total seats. The TMC had won 34 per cent seats uncontested.
Roy (42), who was a government school teacher at Rahatpur High Madrasa, was deployed as a presiding officer at an election booth in Itahar area in North Dinajpur district. He went missing on the polling day and his body was found a day later on the railway tracks.
Candidates claimed that the man was part of the group that barged into Sudhir Chandra Lal Memorial College, the counting centre for Krishnagunj block, and disrupted the counting. They claim the group had the backing of the ruling TMC.
