West Bengal Food Supplies Minister Jyotipriyo Mullick on Saturday claimed that his car was attacked by CPI(M) activists in Birati area of North 24 Parganas district.
The CPI(M) has termed the allegation as baseless.
The incident took place when Mullick's convoy came in the way of a CPI(M) rally, police said.
"The CPI(M) cadres damaged my car. They even tried to attack me. I have lodged a police complaint against its leaders," Mullick said.
Senior CPI(M) leader and MLA Tanmoy Bhattacharya denied the charge. "No such incident happened," he said.
