Alleging that 'atrocities' were inflicted on Trinamool workers by a section of Election Commission officials and central forces in the recently concluded assembly elections, the party leadership is scouting for options for registering protest against the poll body.

"A section of the Election Commission and some of its officers especially those who were controlling the central forces created havoc during the polls. It is because of them that we have got five-six per cent less votes in Kolkata and nearby areas.

"The officers in-charge of central forces had created a separate command all together. This is unprecedented. We will move to bigger platforms to seek justice against the atrocity that was unleashed on us during the polls," a senior TMC leader said on condition of anonymity.

"They have acted in a big brotherly manner against us. Just a day before the April 30 elections, the central forces threatened voters and asked them not to come out for voting on the following day,' the TMC leader said.
