"I did not report to work during the strike and later participated in a CPI-M rally. While returning, around 20-30 people attacked me, asking me why I participated in the strike," Gopal Majhi, the victim, said.
Majhi's family filed a complaint on Friday at the Kulpi police station.
"We have registered a complaint against some unknown persons for attacking Majhi. We are probing the incident and hope to apprehend the culprits soon," a police officer said.
"My father's eye has been completely damaged and he has been severely beaten by Trinamool supporters. We hope the attackers are arrested soon," Majhi's daughter said.
The incident comes a day after a panchayat worker's ear was chopped off in Jalangi in Murshidabad district, allegedly by supporters of the ruling Trinamool Congress for not attending office for a day during the two-day nationwide strike.
That incident was condemned by the Congress and the Bharatiya Janata Party.
"The incident is deplorable to say the least. Day by day the law and order situation in state is deteriorating and the ruling party is responsible," state Congress president Pradip Bhattacharya said.
"The incident is a reflection of the fascism of this government. It seems we are under a dictatorial regime," BJP national executive member Tathagata Roy said.
