The policeman also beat up the bar manager and waiters, said Umesh Karkera, owner of the restaurant in Thane's Kalwa.
"Our crime was that we gave them a bill for their food and liquor. Their action has been caught on the CCTV camera. We have the proof," he said.
He added that the policemen frequently visit his restaurant. "They order alcohol and always pay half the price shown on the menu. We never say anything. Even on that day, they ordered food and alcohol and asked for the bill. However, when they received the bill of Rs 2,000, they got angry and one of them started assaulting us," Mr Karkera said.
He immediately approached the police and filed a complaint, but no FIR has been registered yet.
In the complaint, Mr Karkera has named the accused policemen.
He also spoke about the incident on Twitter and tagged Maharashtra Chief Minister Devendra Fadnavis in his tweets. He has been called to record a statement this afternoon. The Thane Police have not commented on the case.
