Clashes broke out during Central Co-operative Bank's voting at Raiganj in North Dinajpur district today in which seven persons were injured and CCTV cameras were damaged.
Trouble began after 15-20 anti-socials barged into the Zilla Parishad conference hall where representatives of cooperative societies had started assembling for voting.
A police officer said the anti-socials pelted stones, hurled bombs and the police used rubber pellets to disperse them.
Seven persons, including the IC of Raiganj police station and a police constable, were injured in the incidents.
Five of the injured were admitted to a Raiganj hospital from where two persons have been referred to North Bengal Medical College and Hospital in New Jalpaiguri.
The IC was admitted to a nursing home while the constable was discharged after first-aid.
He, however, did not divulge the identity or political affiliation of the anti-socials.
Fifteen CCTV cameras were also damaged by the anti-socials.
The CPI(M) alleged that a few of the TMC staff tried to prvent the voters from casting their votes, which prompted the violence.
