Stones were thrown at West Bengal BJP President Dilip Ghosh's car outside his residence in Kolkata on Sunday but the leader was unharmed, the state BJP leadership said.
The windscreen of the vehicle was damaged in the attack.
"Some unidentified miscreants pelted stones at my car this morning when I was about to leave for Hoogly. The windscreen has been cracked. We have lodged a police complaint in the matter," Mr Ghosh said.
Claiming that there have been multiple attacks on him in recent months, Mr Ghosh said neither he nor his party will be cowed down by these attacks.
"My vehicle and my convoy have been attacked a number of times. Some of our party leaders were also manhandled. But we are not scared. We will fight it out," he added.
