"We have set up an inquiry committee to look into the matter and allegations," a senior official of the Barrackpore commissionerate said.
Singh had yesterday alleged that a group of 30-40 policemen under an ACP had attacked his vehicle in front of the Baranagar Police Station with lathis.
He had also questioned whether it was a ploy to kill him.
Singh today submitted a complaint to the police commissioner of Barrackpore commissionerate.
DC, DD Barrackpore Police Commissionerate C Sudhakar, had yesterday denied the incident saying the police were only doing routine checking.
"Nothing of that sort happened. Only his respect might have been hurt but we apologised," the officer had said.
