"I was on my way to attend a function in Haripal when some people came to me and complained that they were needlessly baton charged by the police. I assured them that I will talk to the police officials and enquire about it when suddenly some stones were thrown at my car," Singh said after the incident.
However, Singh claimed that he was unaware as to the reason for the baton charge.
Trinamool Congress accused Communist Party of India-Marxist (CPI-M) supporters of creating ruckus. Meanwhile, Singh has ordered an investigation into the matter.
