A brick kiln worker was seriously injured and his eye severely damaged after he was attacked allegedly by Trinamool Congress supporters for participating in the trade union strike of Wednesday and Thursday and marching in a CPM rally.
The incident occurred at Kulpi in West Bengal's South 24 Parganas district Thursday night.
"I did not report to work during the strike and later participated in a CPM rally. While returning from the rally, around 20-30 people attacked me, asking me why I participated in the strike," Gopal Majhi, the victim, said.
Mr Majhi's family Friday filed a complaint at the Kulpi police station.
"We have registered a complaint against some unknown persons for attacking Mr 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," Mr Majhi's daughter said.
Mr Majhi is currently admitted to the Calcutta National Medical College Hospital.
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.
