Kolkata: Trinamool Congress leader Prasun Banerjee on Wednesday allegedly slapped a traffic policeman in Kolkata.

The traffic constable claimed that Banerjee lost his cool when he was stopped from taking a wrong U-turn in Kolkata’s Lake Town area, where there was heavy traffic.

Banerjee's driver started arguing with the policeman once the cop stopped him. The MP then told the policeman that a lawmaker should not be stopped.

When the policeman insisted that he should follow rules, the MP allegedly slapped him.

This incident comes days after a man was charged with attempt to murder for slapping Chief Minister Mamata Banerjee's nephew Abhishek Banerjee at a public meeting.

Kolkata in the recent past has seen gross violation of rules by law-makers.

Police are helpless, as they are the onew who face the ire of politicians when they try to do their duty.
