A purported video from Sitalkuchi in Bengal's Cooch Behar is doing rounds on social media.
Four villagers had died in the area in an altercation with CRPF jawans during the fourth phase of polling.
Ruling TMC said video vindicates its position that there was no provocation for CRPF to fire.
TMC MP and spokesperson Derek O'Brien went on to dub it as cold-blooded genocide.
The video shows many locals gathered in a field, while some are seen wielding sticks.
In the viral video, some central force jawans can also be seen.
Soon firing can be heard, though it is not clear who fired the shot.
Video shows a ruckus erupt in the area after the shots are fired.
Earlier, Cooch Behar SP had said there was rumour that police opened fire.
Debasish Dhar had added that the rumour led locals to come out in large numbers.
The SP had said that this led the Central forces to open fire in self defence.
